Baby number two greeted Kelso and Jackie on Wednesday.

Yes, Mila Kunis and Ashton Kutcher are parents for the second time after they waved hello to their new addition, a son, on November 30th.

The name of the baby boy has yet to be revealed, and joins 2-year-old Wyatt Isabelle. Kunis' rep confirmed the arrival to E! News after multiple sources reported on the birth.

Kutcher previously opened up about the baby number two on the Today show, revealing that his daughter was well aware that her little bro was coming.

"She points to Mila and she's like, 'baby brother' when she points to the belly and then she points to dad and she goes, 'Beer!' So I think she gets there's something in the belly but I don't quite think that she knows that it's not going to be a plastic doll yet," he said. "I'm a little terrified to be honest," he added, while smiling. "It's intensely scary."

Congrats to the two!
