Maggie Gyllenhaal and Peter Sarsgaard welcome daughter Gloria Ray
The couple have been together since 2002 and married in 2009 in Italy.
Gyllenhaal recently told USA Today how hard it is to keep your pregnancy under wraps when you're constantly in the public eye.
"I find it difficult to pretend you're not pregnant, which I had to do. I didn't let anyone know until three and a half months this time. I went to film festivals. I'm throwing up in the bathroom and having to keep pretzels in my purse, and having to fit into dresses," says Gyllenhaal.
Congratulations to the whole Gyllenhaal-Sarsgaard family!
