Mila Kunis looks amazing for having given birth just two months ago. During a visit with Craig Ferguson on the Late, Late Show earlier this week, she credited breastfeeding with giving her back her post-pregnancy shape. Ferguson complimented the former That 70s Show star on her svelte shape.

“Breastfeeding is a great workout,” Mila Kunis said. She looked toned and sexy in a black sleeveless dress, and admitted that she simply “eats a lot–that’s what keeps me going through the day.”

Check out Mila Kunis’s conversation with Craig Ferguson on the Late, Late Show. Did you know that breastfeeding really can help women regain their pre-pregnancy shape? Nursing moms burn lots more calories than those who don’t nurse their babies.

Kunis joked about the future, talking about daughter Wyatt and the teen years.

“Not my problem. That’s Daddy’s problem,” she shared, referring, of course to her fiance and baby daddy Ashton Kutcher.

Mila Kunis spends most of her time at home since Wyatt’s birth. Her visit to Craig Ferguson’s show was to promote her upcoming film, Jupiter Ascending. She seems to like home best these days, however. She and Ashton Kutcher spend lots of time ‘making memories’ with their baby girl.

“Nowadays, people can’t do that. Everyone [in the household] has to have a job,” she explained, adding that Wyatt will always be by her side once she returns to work.

In addition to Mila Kunis, Jupiter Ascending also stars Channing Tatum and Eddie Redmayne. It is scheduled to open in U.S. theaters on February 6th.

Will you be checking out Mila in her new film? Ashton Kutcher is no doubt checking her out on a daily basis–likely very pleased that breastfeeding has returned her body to its previous sexy shape.
