The ‘Black Swan’ actress – who started dating her former ‘That 70s Show’ co-star in 2012 and got engaged to him earlier this year – gave birth to a “healthy” baby girl at Cedars-Sinai Medical Centre in Los Angeles on Tuesday night (30.09.14) and a friend told Us Weekly that the couple are thrilled with their new arrival, whose name has not yet been revealed.
Meanwhile, a number of stars have sent their congratulations to the couple.
Robert Downey Jr. – who has sons, Indio, 21, from his first marriage, and Exton, two, with wife Susan – joked it seemed as though the actress had been pregnant for “three years”.
Speaking at the premiere of his film ‘The Judge’, he told ‘Entertainment Tonight’: “When you’re in the public eye, it seems like you’re pregnant for three years.
“So I’m glad that she’s finally past that point . Congrats.
His wife, who is expecting the couple’s second child together, added: “I hope it all works out well. It’s tiring, but it’s the best thing ever.
And his co-star in ‘The Judge’, Billy Bob Thornton – who has three adult children, two sons and a daughter from previous relationships, and 10-year-old Bella with current partner Connie Angland – warned the new parents they will be very protective over their little girl.
He said: “Way to go Mila, that’s awesome. My daughter is 10 years old and the apple of my eye, the centre of my universe. Girls do something to you. You stay very protective.”
