She's known for her killer legs and million-dollar smile, but Cameron Diaz is suddenly taking after her beefy baseball beau -- she's got amazing guns!
After working out with her man Alex Rodriguez at a Venice, Calif. gym on Thursday, Diaz, 38, showed off her super-buff, muscular arms. (Another superstar who's flaunted her own ripped biceps? Rodriguez's ex girlfriend Madonna.)
But how does the Green Hornet actress stay in such fighting shape? She hits the gym (often with pro Teddy Bass) five times a week. Her usual routine: a two-mile run, 30 minutes of Pilates and strength-training moves like squats and lunges.
