Baby Boomers Gisele, Megan And Drew

Gisele Bundchen hasn't personally confirmed that she and her NFL star hubby Tom Brady are expecting their second child, but it does appear that the sexy supermodel was doing her best to hide a burgeoning baby bump in Rio de Janiero, Brazil.  The Victoria's Secret model covered up her famous body with a baggy T-shirt and jacket, but she also tried to elongate it with skinny jeans and high wedge booties. However, she couldn't lengthen her lean figure enough to hide her bump. 

Megan Fox is another beautiful babe who is keeping mum about being an expectant mom. However, sources have come forward to say that she's preggers, and late last month she was photographed trying to cover her tummy by pulling a loose-fitting black cardigan over it. If that wasn't enough evidence, last Saturday her hubby Brian Austin Green was photographed protectively putting his hand on her belly. The "Transformers" actress has said that she'd love to be a mother in the past, but for right now this extremely private couple is keeping their lips sealed about a baby being on the way.

Drew Barrymore was also photographed trying to keep her baby bump covered up even though she's already shown it off. Perhaps she's still trying to adjust to her changing body and just didn't feel like rocking her new belly bulge at her first red carpet appearance after her wedding and pregnancy announcement. She attended the "A Friend for the End of the World" premiere wearing skinny jeans and a very baggy black jacket.

But these three ladies aren't the only celebs who have started baby talk with their obvious bumps - a few other stars have had to deal with pregnancy rumors recently. Last week Kate Middleton sparked rumors that she might be knocked up by wearing a thick wool coat and holding a clutch in front of her stomach. Prince William has said that starting a family is his number one priority, but Kate is allegedly getting upset about being on baby bump watch.

George Clooney's girlfriend Stacy Keibler also got put on pregnancy watch when she was spotted sporting what appeared to be a tiny baby bump. However, one of Stacy's pals blames the bump on a bad camera angle. Plus George has made it clear that he never wants kids (seeing what Angelina Jolie and Brad Pitt have to go through on a daily basis has probably made him even more adamant about not becoming a father).
