Mila Kunis, 31, and Ashton Kutcher, 36, have reportedly welcomed their first child into the world. The Jupiter Ascending actress, who started dating her former That ’70s Show co-star in 2012 and got engaged to him earlier this year, is said to have given birth to a baby girl at Cedars-Sinai Medical Centre in Los Angeles on Tuesday night. A source close to the couple told gossip website TMZ.com that the couple were taken straight into the delivery room after arriving at the hospital at 6am on Tuesday morning. The insider said they arrived alone, without any family members or assistants. The baby’s name has not yet been revealed to the media.
