14. Serena Williams
When she’s playing tennis, Serena Williams is one hell of a beast, having practically won every championship title there is. It’s gotten to the point where her fans are wanting her to compete with the men because watching her go against the women is almost too easy for Serena, who overpowers her opponent with her physique alone. But away from her defined muscles and her aggression when she’s solely focused on winning a tennis match, Williams is just another regular girl, who really tends to enjoy having a good time. She’s friends with so many people in Hollywood — most notably Beyonce, who invited her to shoot the “Sorry” video with her. To this day, Serena can’t believe she’s not only worked with Beyonce but can also consider her one of her closest friends in Hollywood. Not exactly someone who gives off this tough image, right?
