Bikini Shot of the Day: Rebecca Romijn Shows Off Her Birthday Bod

Actress and mother of two strips down to some skimpy swimwear during a photo shoot

Well, here's one great way to celebrate turning 39.

Rebecca Romijn, who just had a birthday over the weekend, certainly proved that age is nothing but a number by flaunting her fabulous figure in L.A. last Friday.

The X-Men actress—and mother to nearly 3-year-old twins—was spotted sporting some skimpy swimwear while posing for pics for an upcoming cover of Fitness magazine.

Throughout the photo shoot, Jerry O'Connell's better half made a few wardrobe changes that included both the bikini seen here as well as an all-white crochet two-piece.

Sure, Rebecca may have been the birthday girl. But clearly we're the ones receiving the gifts.
