Not the fight over Britney's fortune and their two sons....According to the Washington Post, Federline is to take on World Wrestling champion John Cena. The fight will take place on New Year's Day in Miami. Federline, whose rap career never took off, is already talking as if he's the winner. He said "The real Kevin Federline never backs down from a challenge." The 28-year-old signed a contract with the WWE to appear in some fights and was even body-slammed by John Cena in October. Federline is convinced that their next date in the ring will have a different outcome. He said, "Make all your jokes, because New Year's Day I'M the one who is going to be laughing." Britney Spears officially filed for a divorce on November 6th. Both Spears and Federline have asked for full custody of their two sons Sean and Jayden. |
