In an Instagram post Wednesday, Jessica Alba, 36, announced that she and her husband Cash Warren are expecting their first baby boy. In the Boomerang video, Alba and her two daughters, Haven Garner, 9, and Honor Marie, 6, are standing underneath a cardboard box that opens up to pour blue confetti and streamers all over them.

“@cash_warren and I couldn’t be more thrilled to announce… #officiallyoutnumbered #babyboy#cantwaittospoilhim #hugsandkissesforlife#soontobemamaofthree,” Alba captioned the clip.

During an interview on the Tonight Show Starring Jimmy Fallon, Alba opened up about how excited she and her family are to have a baby boy on the way.

"We're like super stoked," Alba told Fallon. "It's going to be a whole situation." As excited as she is for her new baby boy to arrive, Alba admits she has been having some cravings lately. Even though pretty much all mothers go through the same phase of wanting to eat their favorite meal all the time, Alba also said she's trying not to put on too much baby weight.

"I didn’t think I was craving anything until I realized I’m craving Japanese food all the time,” Alba told Fallon. “I actually dream about desserts, but I’m actually trying not to gain so much weight with this baby, so I just dream about them. I want all the shaved ice with like ice cream on the bottom. That’s like my thing."

Dreaming about delicious foods might work for Alba when it comes to satisfying her cravings, but most women with pregnancy cravings would probably beg to differ.

Alba and Warren, who have been married since 2008, officially announced they were "going to be outnumbered" with a third baby on the way in an Instagram post back in July.

When it comes to baby names, Alba already has some strict requirements. "[Cash] was like, 'We should name it Dick with a silent H," Alba added. "He thinks it's like old school. I'm like, 'No it's not." The soon-to-be mother of three insists her new baby's name will start with an H and be unique like her husband and daughters' names. "[It] has to be a word, can’t be too weird. It has to be an H!"
