Jessica Alba and husband Cash Warren expecting third child

Actress Jessica Alba is expecting her third child with husband Cash Warren, she announced on Instagram.

"Cash and I are officially going to be outnumbered. #babyonboard #herewegoagain #blessed" Alba, 36, wrote.

Alba and Warren are already parents to two girls: Honor, nine, and Haven, five.

The boomerang Alba posted for her pregnancy announcement shows her daughters holding balloons of the numbers one and two. Alba, hiding behind a "three balloon," peaks out from behind it with her hand on her baby bump and an open-mouthed smile.
