CHICAGO — Olympic gold medalist Michael Phelps says he'll do "anything" to help Chicago win the 2016 Summer Games.

The world-famous swimmer also says he's "more excited" than nervous about his upcoming stint hosting the season premiere of "Saturday Night Live."

And Phelps tells The Associated Press he wouldn't be surprised if he ended up wearing his iconic Speedo swimsuit on the show, adding that he'd probably be most comfortable in it.

Phelps did a round of media interviews Wednesday after taping the season premiere of "The Oprah Winfrey Show" in Chicago with more than 170 other Olympians.

Phelps won eight gold medals at the Beijing Olympics last month, and Chicago Olympic organizers are banking on the athlete's support of their bid.
