Jaimee Grubbs '2-Timed Woods with Clooney'

Jaimee Grubbs was hooking up with George Clooney during her affair with Tiger Woods, according to a source. The pair met while Grubbs was working at the Stone Rose Lounge in Los Angeles—one of Clooney's favorite haunts—and were often seen in public, the source tells E! Online. "I know him" is all Grubbs says on the subject, while a Clooney rep denies the actor ever met her.

Grubbs appeared on Extra last night and offered an apology to Woods' wife, Elin Nordegren. "I couldn't describe how remorseful that I am to have hurt her family and her emotionally," she said. Woods is an "amazing guy despite everything that is coming forth," Grubbs said, admitting that she was devastated to discover that she wasn't his only mistress.
