Miley Cyrus has pulled out of a red-carpet party at Disney World after topless pictures of her appeared this week.

The star of Hannah Montana was due to appear for the media at a charity event called the Disney Channel Games. Reports say Miley has been at the Florida theme park on Thursday (May 1) to meet fans and sign autographs but is leaving before the big planned event.

Vanity Fair released photos of Cyrus- taken by Annie Leibovitz- this week which showed her apparently topless. The Hannah Montana star then apoligised to shocked fans and said she was embarrassed by the shots.
