In her first interview since giving birth to her daughter Wyatt two months ago, Mila Kunis opened up about who will have to worry when her little girl becomes a teenager.

"The Late Late Show" host Craig Ferguson joked that girls are easier until they become teens.

"That's not my problem! That's daddy's problem!" Kunis, 31, joked right back, referring to her fiance Ashton Kutcher.

Ferguson had joked that at just 9 weeks old, a baby girl was still nice and wasn't running around yet.

"She's not lethargic ... She moves!" Kunis added.

Kunis and Kutcher welcomed Wyatt back in early October and the couple announced it on Kutcher's site Aplus.com.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy," he wrote.

The pair, engaged early in 2014, initially kept quiet about the pregnancy. Kunis, 31, addressed the rumors in May and confirmed she was expecting.

According to E! News, Kunis added last night on "The Late Late Show" that she looks great only weeks after delivering because "Breastfeeding's a great workout!"
