Congratulations are very much in order for Uma Thurman and Arpad Busson.
The actress gave birth to her third child on Sunday night, multiple sources confirm, a girl whose name and measurements are being kept a secret for the time being.
But "Mom and baby are doing well," a rep for the actress says in a statement.
It's Thurman's first kid with Busson, a financier she started dating in 2007, split briefly with in 2009 and has been steady with every since.
Busson has two children himself with Elle MacPherson - sons Flynn, 14, and Cy, nine-and-a-half - while Thurman plays mother to daughter Maya, 14, and son Levon, 10, with ex-husband Ethan Hawke.
