Entertainment Movies Will Smith Reveals He Became Famous to Get Revenge on a Cheating Ex-Girlfriend Will Smith says he vowed to become famous after finding out his high school girlfriend was cheating on him By Mike Miller Published on December 2, 2015 05:20 PM Share Tweet Pin Email Photo: Kevin Winter/Getty Take that, Will Smith‘s ex-girlfriend! Talking about what motivated him to become an actor, the Concussion star revealed that a serious case of teenage heartbreak drove him to seek fame. “When I was 15, my girlfriend cheated on me,” Smith, 47, told Benicio Del Toro on Variety‘s “Actors on Actors” series published Tuesday. “And from that moment, in this bizarre psychological twist, I wanted to be the most famous entertainer on Earth.” At the time, he says, “I believed that your girlfriend couldn’t cheat on you.” Smith made quick work of his vow to become famous. He had a hit rap song on the radio before he was even out of high school, and won his first Grammy in 1998, just five years after the breakup. Two years later he was cast in The Fresh Prince of Bel-Air.

He’s also been nominated for four Golden Globe Awards, two Academy Awards, and has four Grammy Awards to his name. His latest film, Concussion, hits theaters Dec. 25.
