Hollywood actress Uma Thurman has become the proud mother of a baby girl.
The baby arrived on Sunday, said a source. No other information was immediately available, reported Us magazine.
It's the third child for the 42-year-old actress, who has two children -- Maya, 13, and Levon, 10 -- with ex-husband Ethan Hawke, and her first with financier beau Arpad Busson.
The Bill Bill star and Busson, 49, called off their engagement in 2009, but reunited last year.
"Uma was definitely not planning on having another kid. It was a surprise. But she's over the moon about it, very excited," said a source when the news of Thurman's pregnancy broke in February.
Thurman and her daughter-to-be were feted at a small baby shower in New York City May 31 thrown by her half-sister Taya Thurman.
Among the two-dozen guests at the baby pink-elephant themed bash were Thurman's Smash costars Debra Messing and Will Chase.
