Tiger Woods (pictured) has not finished a tournament atop the leaderboard in 18 months. Nonetheless, Forbes says the world's former No 1 golfer remains the biggest celebrity in the sports world.

Woods is No 6 on Forbes' annual "Celebrity 100" compilation of the most powerful people or groups in the entertainment business, the highest rank of any of the 19 athletes who made the list. Miami Heat star LeBron James is 10th, up 18 spots from a year ago, and the Los Angeles Lakers' Kobe Bryant was at No 14 for the second straight year.

Lady Gaga tops Forbes' overall rankings, followed by Oprah Winfrey, Justin Bieber, U2 and Elton John.
