Tiger Woods’ ex, Rachel Uchitel screwing rehab buddy Jeremy London?

[HMG] – With her high profile romance with Tiger Woods a matter of history Rachel Uchitel is now suspected of stealing another girl’s man — her fellow ‘Celebrity Rehab’ star, Jeremy London.

Jeremy’s wife, Melissa Cunningham has told Radar she believes the ex ‘Party of Five’ actor got involved with Uchitel while filming the show. Jeremy, however, denies this — In the most hype-flavored, self-serving terms you ever heard;

“I’m very protective of Rachel because of our friendship,” he says. “She’s been wrongfully persecuted by the media and because of what the media has done to me after I was nearly murdered, I relate to her.”

Married in  September of 2006, Jeremy and Melissa have had four stormy years, but things finally snapped when they were allegedly kidnapped on June 10. The couple checked into rehab together after that day, and have since separated.

“She had to get out of L.A. and the Hollywood scene,” says a friend.

But another source claims the split happened because Melissa discovered Jeremy and Rachel had a sexual connection, and she went crazy on him.

“Rachel and I are good friends — period,” claims London “Melissa has no idea what she’s talking about. Rachel is an amazing, intelligent and sensitive person; she’s human, with human feelings.”

But Melissa has since told reporters she and Jeremy are legally separated, and there’s no chance of a reboot.

“Rekindling our marriage is out of the question,” she said. “But I want him to be a supportive father to our son.”

And if Melissa’s worried about Jeremy’s social life, she may have good cause — When filming for ‘Rehab’ was over, Uchitel, 35, checked into a sober living facility in Malibu – right next to where Jeremy’s staying.
