Rebecca Romijn -- The Bikini Heatwave

With temperatures only in the '50s in L.A. this weekend, it was up to gorgeous Rebecca Romijn to bring on the heat in her sexy two-piece bikini.

The 39-year-old mother of two braved the cool weather and showed off her smokin' hot body while on a photo shoot.

Jerry O'Connell is the luckiest man alive.
