JGarnerPreg0104Part2_05460.jpgJennifer Garner and Ben Affleck are adding to their adorable family!

The A-list couple, who celebrated their sixth wedding anniversary in June, are "thrilled" to be expecting their third child, their rep confirms to the Associated Press.

They also have two daughters, Violet, 5, and Seraphina, 2.

Despite several months of denials from Jen's camp, we've suspected the Arthur actress has been preggo for quite awhile.

The usually svelte Garner has been sporting a noticeably fuller tummy since May, and we knew it was only a matter of time before a special announcement came.

Congrats to the happy pair!
