Is Brad Pitt fat? Is Brad Pitt getting fat? I doubt it, but while Angelina Jolie is the one carrying twins, allegedly, Brad Pitt is gaining a lot of weight and some claim that Brad has gained about 20 pounds since she got pregnant.

According to some experts, it is not surprising that Brad has gained some weight – Jolie is pregnant with twins, and it seems he may be gaining what experts call “sympathy weight.”

“When your significant other is eating for more than one, it’s very easy to want to share with her all her delicious delights,” says one expert. In a recent phone call to a friend, Brad admitted that he now has love handles. “I’m getting bigger than Angie,” he joked to the pal. An insider claims that Brad or has gained about 20 pounds, and the pal ads that he has gone up a pant size.

“He’s not fat, but he does have a paunch,” the pal says. “Brad orders a pizza for the kids and one for himself and settles in with a bunch of DVDs,” the insider says. “After Angelina goes to bed, he polishes off the kids’ leftovers and has ice cream for dessert.”

Angie has noticed Brad is getting fat and has told him to watch what he eats, but Brad cannot help himself. “He says to the kids, ‘Shhh, don’t tell Mom,’” the insider says. “He knows he’s not going to get obese,” the pal adds. “He’s enjoying Angelina’s pregnancy and thinks it’s funny.” [source: In Touch]
