Mila Kunis gave her first interview since welcoming baby girl Wyatt with fiance Ashton Kutcher in September on “The Late Late Show with Craig Ferguson” on Wednesday.

The 31-year-old actress, who looked beautiful in a little black dress with cutouts, sat down with Ferguson to discuss life with her nine-week-old daughter.

When the late night host said that girls are easy to raise until they become teenagers, Kunis joked, “That’s not my problem. That’s daddy’s problem.”

Kunis also confirmed to Ferguson that she is nursing, and credits breastfeeding for helping her lose pregnancy weight.

“Breastfeeding is a great workout,” she said.

Kunis and Kutcher were cryptic when it came to revealing the first photo of baby Wyatt: Kutcher took to his website, aplus.com, to share a photo of his daughter, along with photos of five other babies and two animals.

“Here’s your baby photo. Well, one of them is. Now can the helicopter please stop hovering over our house, there is a baby sleeping inside! And she’s super cute,” he wrote.
