She's played a mom on the big screen, but now Toni Collette is ready to embrace the role in real life. The Little Miss Sunshine

This is the first child for Collette, 35, and her husband of four years, musician Dave Galafassi.
"All are well and very happy!" says Collette's rep.
Collette was just as joyous when she announced she was pregnant

"It is strange, the last three films I've done I have been pregnant," Colette added. "I'm just like, what is the universe trying to tell me? But I think everything happens when it's meant to."
