Another duckling! "Duck Dynasty" stars Jep and Jessica Robertson are proud parents again after adopting a baby boy.

The couple introduced their new son, Jules Augustus, on the Jan. 20 series premiere of their show "Jep & Jessica: Growing the Dynasty."

Shortly after, Jep took to Twitter to show a photo of his son.

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

The family's reality show, a spin off of the wildly popular "Duck Dynasty," chronicles the couple as they finalize their adoption.

Jules joins the couple's four biological children, Lily, Merritt, Priscilla and River.

On Jan. 21, Jep updated his Twitter bio to, "Happily married father of 5!"

In an interview with Fox News, Jep said Jessica was on board with the whole having-another-child thing long before him, but after going on a missionary trip to the Dominican Republic and seeing orphaned children, it changed his thinking.

"It was all God's plan to bring [Jules] into our lives at the right time," Jessica said. "We've kind of been waiting a long time for a baby to come into our lives."

The couple's four children are all in on their new brother, too.

"They absolutely love it," Jep said, "they're always kissing on him, hugging on him."

Last month, Jessica told Rebel Country that she felt encouraged to adopt after seeing the less fortunate.

"The past few years with Duck Dynasty, our eyes have been opened and we've seen a lot of kids that are in need," she said. "Knowing that we can make a difference and take a child in that maybe would never have a mommy or daddy, you're changing a child's life forever. And he's going to change our life forever."
