Jessica Simpson very cutely announced her third pregnancy with some help from her two older children. The singer posted two photos on Instagram yesterday with the big reveal, and it was an unexpected and happy surprise for fans.

The first picture is of her two older children, daughter Maxwell, 6, and son Ace, 5. They're both smiling and adorably posing with two large black balloons with polka dots. The caption simply reads, "Surprise." The next photo came soon after with the big balloons popped, announcing her pregnancy and revealing the gender of the new baby. Spoiler alert! The balloons were pink, which means Jessica will be welcoming a second daughter. The caption of this post confirmed the joyous news and said, "This little baby girl will make us a family of five. We couldn’t be happier to announce this precious blessing of life."

It was a beautiful announcement and the gender reveal was done so well. Her kids were looking at the pink balloons floating away with surprise and wonder making it all the more precious.

Jessica also gave us a peek at her growing baby bump. She posted a photo of herself with her signature long blonde hair and oversized sunglasses. We don't know the due date yet but she looks great!

Simpson and her husband, former NFL player Eric Johnson, have been together since 2010. She gave birth to their first child in May 2012 and to their second in June 2013. Back-to-back pregnancies can be rough and so can the first few years of any child's life. This is why it seemed as she was done having kids and their family was complete. Jessica even famously said on The Ellen Degeneres Show that she was not going to have a third child. This was just a year ago, and we are wondering what changed her mind!

Congratulations to the whole family! We're sure this baby will be just as adorable as her two older siblings. She also has two built-in helpers with her children being a little bit older.
