Believe it or not, in amongst this list of celebrities, who you may not be aware are grandparents, there are two amazing great grandparents. Do you think you would have been able to guess who it was unless we told you? These famous celebrities may surprise you because many of them don't seem old enough to be grandparents yet. Some were so incredibly young when they added grandparent to their list of achievements. And I most certainly believe that being a grandparent is an amazing and wonderful achievement

It's very easy to see celebrities as not real people considering we watch their lives through our TV screens and magazines. But they are real people with real families. With children of their own, many of them have now stepped into the world of being a grandparent and lavish attention on their children's kids. It's beautiful to see a famous grandparent happily walking with their grandkids as normal as you and I. Amazingly though, some of these celebrities were incredibly young when they became grandparents and it might shock you to discover just who has little grandkids running around now.

15 Dave Bautista

Did you know that the 45 year old WWE star and Guardians Of The Galaxy actor is not only a dad but a grandfather as well? Bautista has two daughters with his first wife Glenda who he married in his early twenties. Their daughters Keilani and Athena were born in the 1990s.

His first daughter, Keilani, now has two children of her own making Bautista one of the coolest granddads around! A proud grandfather, his grandsons, Aiden and Jacob, had front row seats at the premier of Guardians of the Galaxy. Could you imagine telling your school friends that your granddad is the muscle clad hero! Incredibly, Bautista became a grandad before he was even 40 years old. Having had a hard childhood and upbringing, Bautista is adamant that his grandchildren don't face the trials he suffered at their age. What a great role model!

14 Ron Howard

Ron Howard is not only an amazing Dad but also an incredible grandfather. He is an inspiration to his family who he encourages to follow their dreams. He became a grandfather when his daughter, actress Bryce Dallas Howard, had her first child in 2007.

Bryce credits her Dad with helping her to achieve everything she has wanted in life and recalls how he would often say never be "embarrassed by your creativity," in order to encourage her on her chosen path. What a great role model for her oldest son Theo who is 10 and her daughter Beatrice who is 5.

Ron Howard, when talking about his grandson, told parade magazine, "I love being with him. I didn’t remotely understand how profound the experience of being a grandparent is until you become one. It’s interesting, when you become a grandparent you start bumping into other folks who have had that experience. And there’s this sort of wink and a nod like it’s sort of a club or something."

13 Charlie Sheen

Hellraiser, Charlie Sheen became a grandfather in 2013 at the tender age of 47, when his daughter, Cassandra Estevez, gave birth to his first grandchild. Sheen had the honour of walking his daughter down the aisle when she married her fiance, Casey Huffman. Sheen took to twitter to announce that his daughter had given birth to his first grandchild by saying “Hey Luna, welcome to my planet!”

 

Sheen, who has five children of his own, will most certainly make for a very interesting grandfather. He was just 19 years old when his high school sweetheart, Paula Speert, have birth to their daughter. Cassandra was 28 when she gave birth to Luna, making Sheen a very young grandfather indeed. On the arrival of baby Luna, Sheen told TMZ, "It's impossibly a most wondrous day. My bucket list is a thimble!"

12 Nicolas Cage

In July 2014 Nicolas Cage became a grandparent at the young age of 50 when his 25 year-old son, Weston Cage and his wife Danielle had their first child. Cages grandson was born to the famous Cage family and given an incredible name, Lucian Augustus Coppola Cage. Part of Lucian's name comes from Weston's own grandfather, August Floyd Coppola, who passed away in 2009. Since the birth of Lucian, Weston and Danielle have gone on to give Cage a second grandson called Sorin. An equally amazing name.

Weston told ET Online that his dad is a "brilliant" grandparent and went on to say, "I believe that a lot of the morals and philosophies that I will teach to my son definitely comes from my father. He was an amazing father to me."

11 Whoopi Goldberg

Whoopi Goldberg became a grandmother at the incredibly young age of 34 when her daughter Alexandrea had her own daughter, Amarah Skye, when she was just 16. Goldberg herself was just eighteen when she had Alexandrea. But not only that, she can now add the amazing title of Great-Grandmother to her list as Alexandrea herself is now a grandmother.

Amarah gave birth to Goldberg's great-granddaughter, Charli Rose, in 2014. The star took to Instagram to welcome the new addition to the family saying, "Everyone meet the new addition to my family Charli Rose and yea I'm a tad awkward it took me a minute been a LONG time! #thankGod4newlife!" In the Instagram video Goldberg, who is clearly ecstatic at the prospect of being a great-grandmother, declared that she has not looked after a baby in 39 years and was out of practice! We're sure the loving grandmother took it all in her stride.

10 Pierce Brosnan

Did you know that Pierce Brosnan has five children of his own so it is only natural that he is now a grandfather. He first became a grandchild when his adopted daughter, Charlotte, who sadly passed away at the age of 42 from Ovarian Cancer, gave birth in 1998. The grandfather had just been named People magazine’s "Sexiest Man Alive," six years prior to this new accolade! Charlotte made Brosnan a grandfather one more time and his son Sean recently had a baby girl with his wife Sanja Banic in 2015.

Sean and Sanja honoured Sean's late mother Cassandra, who also died of Ovarian Cancer in 1991, when naming their baby girl calling her Marley May Cassandra. Brosnan took to Instagram to welcome his granddaughter saying, "My darling Sean with his baby girl Marley May Cassandra what utter joy to be her grandpa... beautiful life!”

In January this year, Osmond joked that his family were like rabbits as he made the announcement that he will be a grandfather once again. He quipped on ITV's Lorraine, "We're changing our name from the Osmonds to the rabbits."

Osmond has five sons himself, Donald Jr., Jeremy, Brandon, Christopher and Joshua with wife Debra Glenn. He has previously said that family is the core of his life and that his successful marriage to Debra is what helped him through hard times. He said about marrying the woman he loves, "Now I had someone who understood me and with whom I could build a future together."

8 Jim Carrey

Jim Carrey may seem a little young to be a grandfather but he happily embraced the role at the age of 47 when his daughter, Jane, had a baby boy in 2010 with her husband Alex Santana. The couple welcomed their first child, a son, who they named Jackson Riley Santana.

As any proud grandfather does, Carrey took to twitter to spread the news about the new arrival by posting a photo, saying,  "Jackson Riley Santana, My Grandson, Born today! This is what 7lbs.11oz. of Calfornia dynomite looks like!"

Carrey said about being a grandfather, "I love being granddaddy, granddaddy Jim. I just get a lot of joy from that little boy." And added that he was very proud of his own daughter saying, "Jane is going to be a great mom."

7 Tony Danza

Tony Danza has been a dancer, a singer, a professional boxer, an author, an award-winning actor, and TV talk-show host. But none of that compares to his favourite role of being a grandfather. He became a grandpa in 2005 when his grandson Nicholas was born. Danza was in his mid-50s at the time. He told Grandparents.com, "I want to be the guy who takes my grandson fishing and the guy he wants to go fishing with."

Danza has a wonderfully close relationship with his son Marc who he had when he was just 19 years old. The closeness in age has given the father and son a close bond. Speaking about how proud he is of his son Marc, Danza said, "I have even more respect for him. The way he conducts himself with his kid makes me so proud. And I was proud of him before Nicky was born. I love them together. Just the other day they were playing Steamroller on the bed. Nicky was jumping over Marc as he rolled around. It was fabulous. I’m so fortunate to live close."

6 Ozzy Osborne

Ozzy Osborne is no stranger to the role of Grandpa considering he already has four grandchildren from a previous marriage. He has two grandchildren each from his daughter Jessica and his son Louis who are his children from his previous marriage to Thelma Riley.

But now Ozzy and Sharon have two grandchildren of their own as their son Jack and his wife, Lisa, have two beautiful daughters, Pearl and Andy Rose. To add to the motherload, Jack and Lisa have just announced that they are expecting their third child.

Ozzy is notoriously famous for being an absent father in his children's younger years as his rock and roll ways took over. But now, only last year, Jack and Ozzy have starred in a TV show together, Ozzy & Jack's World Detour. The father-and-son duo travelled and explored the world together.

5 Kiefer Sutherland

Kiefer Sutherland who played the terrorist fighter, Jack Bauer in the hit show 24, became a grandfather hen his stepdaughter, Michelle, welcomed a son in 2005 called Hamish Kiefer Sinclair and later a second son Quinn.

Kiefer has previously said about being a parent, "I don't know a single parent who gets through a day thinking, 'I did that perfectly'. We always feel like we screwed up somewhere." And he believes that boundaries are the core to raising centered children. "I really do believe that a parent's responsibility is to create a structure and boundaries for your children, because without them it's very difficult for a child to know what to do," he said.

On being a grandfather, Kiefer hilariously recounted a story that speaks volumes about the type of grandfather he is. "On my lunch break earlier I went out to a gift shop, and bought them two wooden swords," he revealed. "I said to a friend, 'The best thing about being a grandfather is that I get to give them these wooden swords, but I don't have to take them to the hospital to get the stitches done!'"

4 Cee Lo Green

Gnarls Barkley's, Cee Lo Green was a staggering 35 years old when his 20 year old stepdaughter, Sierra, gave birth to a son making him an incredibly young grandfather. The Voice judge and record producer was delighted with the addition to their family despite his new title of Grandpa making him sound older than he is. Telling Chelsea Handler about the new arrival, he said, "I'm a grandfather. I'm 35. She had a son so I have a grandson."

CeeLo has a son, Kingston, and two older stepdaughters, Sierra and Kalah, from his marriage to Christina Johnson which ended in 2005. Cee Lo and his stepdaughter Sierra, featured on MTV's My Super Sweet 16 when Sierra celebrated her 15th birthday with an incredible birthday bash.

3 Harrison Ford

Ford has a young son with wife Calista Flockhart who she adopted in 2001 before her marriage to Ford. He also has two older sons from his first marriage to Mary Marquardt. Finally, Ford also has two children from his marriage to Melissa Mathison, Malcolm and Georgia.

Ford's eldest son Ben is father to Ethan, who was born in 2000, and Waylon who happily arrived in 2010. A notoriously private person, Ford will always try to keep his families personal lives out of the limelight.

2 Mick Jagger

Mick Jagger has not one or two but give grandchildren and amazingly one great-grandchild who arrived in 2014, making him a great-grandfather at the age of 70. Assisi Jagger, Jagger's granddaughter gave birth to her baby girl at the age of 21. But what makes Jagger's family story all the more interesting is the fact that Jagger himself added his own new arrival to the family tree in December 2016 when his girlfriend, Melanie Hamrick, gave birth to their son Devereux Octavian Basil Jagger.

The Rolling Stones frontman may not appear to be a typical grandfather figure but in actual fact he is doing pretty well at it. Marsha Hunt, mother to Mick’s first child said, "Things have worked out pretty well. Mick is a grandfather, and he’s a good one."

1 Tom Hanks
