Yummy mummy Rebecca Romijn always manages to turn heads on the red carpet. While the model/actress favors low-cut and backless dresses (with a body like that, wed wear those styles too!), she also makes basic jeans look sexy.

Romijn is celebrating her 39th birthday this Sunday with hubby Jerry OConnell and daughters Dolly Rebecca Rose and Charlie Tamara Tulip , so check out the gallery for all of her best looks.
