Miley Cyrus dismisses 'cheating' report

London, July 9 (ANI): 'Hannah Montana' star Miley Cyrus has denied reports she's been caught cheating on boyfriend Liam Hemsworth.

She has insisted that it's "not her" in a photo with a mystery man that appeared online.

She acted swiftly after a post on celebrity blog PerezHilton.com showed an image of a young woman in a black bikini reclining on a boat in the arms of a semi-naked hunk.

"That's not her," the Daily Star quoted a representative for the star as telling GossipCop.com. (ANI)
