Mischa Barton dating aspiring actor?

Former OC actress Mischa Barton is reportedly dating an aspiring actor, Leo Wyndham.

"They've been together for over a month now," Contactmusic quoted a source as saying.

"Leo is out there trying to make it as an actor, so they move in similar circles. He's been an extremely positive influence on her," the source added.

Despite claims that her wild partying led to her being cared for on a psychiatric ward, Mischa insists that she was hospitalised after an operation on her wisdom teeth went wrong.

"Really, it was blown out of proportion. It's kind of silly now to be talking about it because I'm so fine now, but it was just a really bad time for me," she said.

"I had two surgeries - I had four teeth taken out and it had gone really badly wrong - they had to drill into my jaw and I was just in excruciating pain. I was having Novocaine shots every day to minimise the pain. It really was rock bottom.

"If you go into the hospital, and you're having a meltdown, and you say something like, 'I feel like I want to die,' they hold you - they won't let you go," she added.
