Uma Thurman, 42, and boyfriend Arpad Busson just welcomed a baby girl!

The couple welcomed the new addition on July 15, Sunday.

“Uma was definitely not planning on having another kid. It was a surprise,” a source said when the couple announced the pregnancy. “But she’s over the moon about it, very excited.”

This is the first child for the couple, but the third for Thurman and Busson respectively. Thurman has daughter Maya and son Levon with ex-husband Ethan Hawke. Busson has sons Flynn and Aurelius with ex-fiancée Elle Macpherson.

The news also comes a year after ex-husband Ethan Hawke welcomed a baby girl.

Congratulations!
