Celeb bump day: Jessica Biel, Maci Bookout, Tamera Mowry, Isla Fisher

Happy Wednesday Hump Day, also known to us as Celebrity Baby Bump Day. We rounded up the cutest pregnant celebrities including Jessica Biel, who finally confirmed her pregnancy with an adorable baby bump picture with Justin Timberlake. Maci Bookout also debuted her baby bump, while Molly Sims looked gorgeous in a colorful maternity dress. Tamera Mowry and Isla Fisher round out our photo gallery of the most buzz-worthy baby bumps of the week.

After months of dodging questions and keeping tight-lipped about the baby news, Justin Timberlake and Jessica Biel confirmed that they are indeed expecting their first child together with this sweet baby bump photo.

Timberlake, who just celebrated his 34th birthday, shared this photo on his Instagram page as he kisses Biel’s pregnant belly. As if he weren’t adorable before, this picture totally upped his hotness factor.

“Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets,” he captioned the photo.

This picture confirmed that, yes, Biel really is pregnant and, no, they aren’t finding out the gender of the baby.

The 32-year-old actress is reportedly due in April, however, she has kept a low profile throughout her pregnancy, concealing her baby bump in loose tops and jackets.

Even though news of her pregnancy became public in October, this is the first time they have spoken out about it.

“Jessica has had tense times in the past when it comes to having a baby, so it is not surprising that she is staying mum on confirming the news publicly yet,” a source revealed.

As their due date approaches, it sounds like the couple can finally relax and gear up to welcome their baby.
