Jennifer Garner has confirmed she's pregnant with her second child. After weeks of speculation, the worst kept secret in Hollywood has been revealed - after Garner's mother-in-law and her former Alias co-star Victor Garber let the baby news slip last month.

The actress says she and husband Ben Affleck are "so excited," adding, "It always makes me laugh when people say 'Is she? Isn't she?' It's like, 'Eventually you will know, so just chill out for a minute."

The celebrity couple already have a toddler, Violet, at home.

Angie Harmon has also confirmed she's pregnant just two weeks after her husband denied initial reports. Former American football star Jason Sehorn shot down the rumours the couple was expecting a third child at a recent fundraiser, stating, "I don't know where this all came from."

But now a representative for the pair has confirmed Harmon, 36, is indeed with child.

She says, "The couple originally denied reports that they were pregnant in an attempt to take back the right to release the joyous news themselves."

Harmon and Sehorn have two daughters, Finley, four, and Avery, three.
