Jennifer Connelly is ready for another little one!

A rep for the actress, who just marked her 40th birthday Sunday, confirms exclusively to that she and hubby Paul Bettany, 39, are expecting.

Connelly is already mom to the duo's 7-year-old son Stellan and 13-year-old son Kai (from her previous relationship with photographer David Dugan).

The star, who wed Bettany in Scotland in 2003 after they met filming the Oscar-winning flick A Beautiful Mind, opened up to Glamour last year about how she knew he was The One.

"It was something about the way that we were together," she told the mag. "He stood out to me as someone singular and rare and beautiful, and I liked the way he was in the world. I liked the way he was with people. I liked the way he was with my son and the way he made me feel."
