The Robertson family just got a little bigger!

Duck Dynasty stars Jep Robertson and Jessica Robertson introduced the newest addition to their family Wednesday on the premiere of their spinoff show, Jep and Jessica: Growing the Dynasty: a baby boy. Jep also turned to Twitter early Thursday morning to show off his son, whom they adopted and decided to name Jules Augustus with a nickname of "Gus."

"Thanks for the love! This has been a crazy, awesome ride but so worth it! Me and Gus signing out! #JepAndJessica," he tweeted.

Their new show has an eight-episode run and follows the reality TV stars as they finalize the adoption process that ultimately led them to taking home their adorable boy. He joins the couple's four other children, Lily, Merritt, Priscilla and River.

"It's like such a surreal moment, to finally have him in our arms," Jessica said on the show. "We waited so long and wanted to happen for so many years, so to actually have him and hold him and know that he's ours and we're his forever family, we're excited."

Jep and Jessica aren't the only Robertsons to adopt a child; Jep's brother, Willie Robertson, and wife Korie Robertson also adopted a son. Although they had their little boy at home with them since May, the couple didn't reveal the news of their adoption until a few weeks ago.

"We've had lots of questions about the cute kid popping up in our photos lately. We are excited to be in the process of adopting a new son!" Korie shared with fans. "He's been with us since May, but we wanted some privacy and time for him and our family to bond before telling the world (It's a bit of an adjustment coming into this big, crazy family, ha)."

For those who may not be loyal watchers of the famous family, the couple adopted 13-year-old Willie Jr. Robertson when he was a baby. Their oldest child, Rebecca Lo Robertson, was an exchange student who became their foster child all the way back in 2004.

Congratulations to the growing families!
