"It's always hard," Jennifer told Access Hollywood of leaving her baby behind for the night. "I [have got to] get adjusted to it because, it's like, I don't [want to] ever leave him. He's so precious."
In fact, Jennifer has been so into being a new mom that she only just found out Ellen DeGeneres is filling the "American Idol" judge's chair, which was vacated this summer by "VH1 Divas" host Paula Abdul.
"I am just now hearing about that. I guess I've been tucked away with the baby because I was like, 'Really?'" Jennifer said of her stunned reaction. "I love Ellen."
And what does Jennifer — a former "American Idol" Top 12 finalist from Season 3 — think Ellen will bring to the table alongside Simon Cowell, Randy Jackson and Kara DioGuardi?
"Humor. Ellen's hilarious and who [doesn't] love her," Jennifer said.
But while Jennifer was happy to talk about Ellen, she was mum on rumors she may return to "Sex and The City 2."
"I don't know. [I'm going to] leave that to Sarah [Jessica Parker] and Michael Patrick King to tell you that," she said. "I don't know."
