She may be hesitant to show off her stunning engagement sparkler from Justin Timberlake, but there is one enviable asset Jessica Biel has no trouble flaunting these days: Her totally hot bod!
As the New Year's Eve actress celebrates her 30th birthday Saturday, Us Weekly rounded up our picks for Biel's sexiest hot body moments over the years.
Admitting in the past that she has trouble sticking to a proper diet and fitness routine, Biel maintains her shape thanks to high intensity workouts. "I have an amazing trainer, Jason Walsh, who I work with two or three times a week," the actress has said. "We do lots of circuit and strength training, especially for my legs and my back, because it's quite weak from years of gymnastics. I concentrate on making everything strong, and you can't do that with just cardio."
