Mila Kunis has given birth to a baby girl, according to reports in the US.
The 31-year-old 'Black Swan' star's fiancé, Ashton Kutcher, 36, was believed to be at her side during the birth on Tuesday morning at LA's Cedars-Sinai hospital.
Sources told celeb US website TMZ that the couple’s baby was delivered “on schedule” at 6am.
It is the first child for the notoriously private couple, who first met on the set of 'That 70s Show' in the late nineties and became engaged in February.
Fans of the new parents were quick to offer their messages of love on Twitter.

In May, Mila told Ellen DeGeneres that her fiancée had stocked up on food in case she had any weird cravings.
"[Ashton] assumed that I was gonna have goofy cravings, so he stocked our secondary fridge with weird food, just, like, pickles and sauerkraut, or, like anchovies and ice creams, just in case at one point during this pregnancy I'd be like, 'I really want something'," she said.
Ashton was previously married to Hollywood star Demi Moore, 51, for six years. They finalised their divorce in November.
Congrats to them both!
