Here's to a very happy birthday to Amber Valletta! The model-turned-actress rings in her 40th year and we're not sure how it's possible, but she looks better than ever! Valletta—who is also the doting mother to 13-year-old son Auden and married to Olympic volleyball player Chip McCaw—first started her modeling career at the young age of 15-years-old and since then,  she has seamlessly transitioned into an actress that we all know and love.

From roles in blockbuster hits including What Lies Beneath starring Michelle Pfeiffer and Harrison Ford, Hitch with Will Smith, and Sandra Bullock's Premonition, Valletta is now most known for her role as Lydia Davis on the hit ABC drama, Revenge“You can dress everybody in the world, but when you start dressing a supermodel who knows how to wear clothes so instinctively, you can take any old dress on a hanger and she makes it look like a three-thousand dollar gown," says costume designer Jill Ohanneson on working with Valletta. "It’s amazing how she can elevate clothes." To be honest, we're not that surprised! To celebrate Valletta's 40th birthday, see more stars who turned 40 in our gallery!
