A topless Mischa Barton revealed her very dimpled thighs as she sunbathed at her hotel in Australia on the weekend

Holidaying in Hamilton Island was a relaxed affair for Mischa Barton, until a snapper caught the OC star sunbathing without her top on.

It was when the 22-year-old actress was spending two days on the Island with her mum, that a paparazzo clicked her sunbaking topless.

"We went out from Hamilton to a tiny island to relax in the sun and all of a sudden Jamie Fawcett jumped out of a bush with a massive camera lens and took photos of me. He'd followed us in a boat!" the Sydney Morning Herald quoted the fuming actress, as saying.

She added: "He's a ridiculous human being. I've never abhorred anyone more. I was so angry I went up to him and said how disappointed I was with his behaviour. He apologised but he was very insincere."
