Mila Kunis, Ashton Kutcher welcome baby girl

Ashton Kutcher and Mila Kunis have reportedly welcomed a baby girl.

Kunis, 31, gave birth to the child on Tuesday at Cedars-Sinai Medical Center in Los Angeles, reported TMZ.

This is the first child for both.

Kutcher, 36, started dating his 'That '70s Show' co-star after finalising his divorce from actress Demi Moore in December 2013.

Kunis recently told W Magazine that she plans to take a year off of acting to become a full-time mother.
