Laura Prepon

Profession: Actress

Age: 31
She played Donna Pinciotti on That '70s Show, and her beautiful red hair, parted down the middle, went perfectly with her spunky character. She posed for Maxim twice, once sporting her natural hair color and more recently in blond, highlighting an interesting phenomenon that other redheads should note: red, for some reason, makes her twos look much larger.
