Los Angeles - Mila Kunis and Ashton Kutcher have reportedly welcomed their first child into the world.
The Black Swan 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 06:00 on Tuesday morning.
The insider said they arrived alone, without any family members or assistants.
It was recently revealed the 31-year-old actress was tired of waiting for her daughter to arrive and was getting desperate to go into labour.
Another insider said: "Mila just wants the baby to come out already! She hasn't slowed down at all. She seems to have a lot of energy."
The couple were disappointed that Mila didn't go into labour while Ashton was on a break from filming Two and a Half Men last month.
A friend said at the time: "They were hoping the baby would come this week because he's on hiatus. He is a nervous wreck."
