Mila Kunis and Ashton Kutcher

Mila Kunis and Ashton Kutcher

Mila Kunis insists Ashton Kutcher will have to deal with their daughter when she is a teenager.

The 31-year-old actress gave birth to the couple's first child, Wyatt, just over two months ago but the raven-haired beauty has already made plans for the 'Two and a Half Men' actor to take control of parenting duties in 13 years time.

When talk show host Craig Ferguson suggested girls are always well behaved until they become teenagers, she said: "That's not my problem. That's daddy's problem! My sister-in-law had a little boy two weeks prior to us having our little girl and it is completely different. Everything."

In her first post-baby interview, Mila admitted she has lost her baby weight thanks to breastfeeding and admitted her and 36-year-old Ashton's little one cannot sit still.

When asked on 'The Late Late Show with Craig Ferguson' how old her daughter is, she replied: "Two months ... nine weeks. She's not lethargic. She moves!"

The star also joked she and Ashton will "absolutely" raise Wyatt Scottish to please Scottish-American host Craig.

Mila also admitted Ashton is a huge fan of the kilt she purchased him on a recent visit to the country.

She explained: "It turned out great, because you know, nothing's under the kilt.

"He loves kilts. The day that I landed, when we got back from Scotland, was on St. Patty's Day. And then we went out to a bar and he wore his kilt and now every St. Patrick's Day."
