Motherhood is Sexy for Rebecca Romijn

New mom Rebecca Romijn still hasn't managed to shed the last bit of weight she gained while pregnant with twin daughters Charlie and Dolly. And the blonde beauty isn't in any hurry to get back down to her original supermodel size.

"I feel as sexy as I have ever felt," Rebecca reveals in a new interview with InStyle. "I’m a jeans size up from where I usually am, but there’s nothing about it that freaks me out — I’ve always said that sexy is having a really strong sense of yourself and never taking yourself too seriously.”

And though the twin girls aren't even six months old, Rebecca and husband Jerry O'Connell are already beginning to see the personality differences. She says that Dolly is "all baby and wants to have one-on-one relationships with people," while Charlie "is always looking around. She can’t wait to be out of this baby body because she’s got a lot to do… Dolly looks just like me, and Charlie looks like Jerry. We got one of each.”
