Congratulations, Mila and Ashton!

Mila gave birth to a baby girl on September 30.

Mila Kunis and Ashton Kutcher have reportedly welcomed their first child, a baby girl, in Los Angeles on the eve of September 30. 

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 6a.m. 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 labor. 

Another insider said: "Mila just wants the baby to come out already!

"Mila hasn't slowed down at all. She seems to have a lot of energy."

The couple was disappointed that Mila didn't go into labor 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."
