Another member of the famous Duck Dynasty Robertson family is going to have a baby! John Luke Roberston and wife Mary Kate McEacham-Robertson are expecting their second child. They are also parents to one-year-old John Shepherd. John Luke and Mary Kate recently shared their announcement with a sonogram photo shoot.

John Luke Roberston, the son of Duck Commander CEO Willie Roberston, revealed to his Instagram fans on Saturday that he is going to be a dad again. John Luke posed with wife Mary Kate, who held son John Shepherd in her lap, along with a sonogram photo. He simply captioned, "Round 2." The couple married in 2015.

Mary Kate also shared a heartfelt announcement post about her first-born on her website The Little Duck Wife and included several never-before-seen photos from the day he was born. "I sat down with the intentions of posting multiple times and was just overcome by emotion from my baby growing," she wrote. "But here I am on his first birthday feeling good and just so incredibly proud and happy. Feeling thankful for a whole year with him."

Duck Dynasty aired on A&E from 2012-2017, following the lives of the Robertson clan, who have earned a fortune from their line of Duck Commander duck calls as well as various merchandise such as appeal, gear, and books. Throughout the years, the family has earned their ranks as being known as having conservative, Christan based values.

This isn't the first baby news to hit the well-known Roberston family. In early October, Luke's younger sister Sadie Roberston and husband  Christian Huff, announced they are expecting their first child-- a baby girl.

BabyGaga recently reported that Sadie has been struggling through her first pregnancy, testing positive for the coronavirus. She described the virus as "terrible, noting that her symptoms included a headache, cough, body aches, a loss of taste and smell, and difficulty sleeping. At one point, her throat was "so red and on fire." Sadie has since recovered from COVID-19 and is doing well.

Sadie also reported to Pop Culture that she is experiencing depression during her pregnancy. "All the physical pain on top of the loneliness of it, the isolation of it, makes you feel this depression that is something that I’d never experienced before," she explained. "I'm not going to lie, I cried a lot. It's really a dark sickness."

Mary Kate gushed on her Instagram about the arrival of baby number two, in a similar sonogram announcement photo reveal. "We are so incredibly excited to be welcoming another sweet baby into our family!!! This new life is such a gift we are so thankful for! Sheps going to be the sweetest big brother," the caption read.

Congratulations, Robertson family!
