Uma Thurman Welcomes Her Third Child

Gilbert Carrasquillo/FilmMagic(NEW YORK) -- Uma Thurman gave birth to a baby girl on Sunday, a source confirmed to US Weekly.

"Uma was definitely not planning on having another kid. It was a surprise," the source said. "But she's over the moon about it, very excited."

The newborn baby makes three for the 42-year-old Oscar nominated actress, who has two children -- Maya, 13, and Levon, 10 -- with ex-husband Ethan Hawke.

The baby girl, whose name hasn't been made public, is Thurman's first child with boyfriend Arpad Busson.
