Jeremy London denies reports of affair with Tiger Woods' 'mistress' Rachel Uchitel

American actor Jeremy London has denied reports that he is having an affair with professional golfer Tiger Woods' alleged mistress Rachel Uchitel.

London, 37, who will be featured with Uchitel, 35, on the fourth season of VH1's Celebrity Rehab with Dr Drew, says he has a lot of respect for her and that he can relate to facing a private crisis in the public eye.

"Without a doubt we are only friends. We never even kissed. We've never had an affair," People magazine quoted him as saying.

He does however acknowledge that he has become close with Uchitel after they both checked into a Pasadena recovery centre, but insists they are "like brother and sister".

"She's an amazing person and [the media] keeps messing with her. I think I can identify with her because of that," London, who made news with a bizarre kidnapping incident, added.
