50 Cent agrees to post nude picture if New York Giants lose Super Bowl

50 Cent has agreed to tweet a naked picture of himself if the New York Giants lose the Super Bowl.

The rapper, real name Curtis Jackson, took up a bet from one of his followers challenging him to post a full-frontal nude photograph of himself if his team loses to the New England Patriots at the American football game on February 5.

"Lets bet. If the Giants lose the Superbowl, u must post ur d**k on the twitter. If they win, I'll post my boobs & face. Bet? (sic)," the fan wrote.

"Ok," 50 Cent responded.

Later in the week, the rapper revealed that he is willing to bet a million dollars on the New York football team.

"I'm up 500,000 off the last one," he tweeted, referring to the two teams' previous match-up in 2008. "ill bet it back Ill put a 1,000,000 on my G MEN."

50 Cent recently launched his own line of headphones.

The Super Bowl, which will feature performances from Madonna and LMFAO, airs on February 5 at 6.30pm ET on NBC.
