Rob Thomas, the hunky lead singer of the hit band Matchbox Twenty, has denied allegations posted on the internet that outrageously claim he had sex with Tom Cruise. Rob even went so far as to say that if he was gay, Tom wouldn't be at the top of his list — Brad Pitt would be!

For several weeks, internet blog sites have posted a false e-mail that alleges the 33-year-old musician slept with Tom shortly before the actor started dating his fiancée, Katie Holmes, in May.

The message also suggested their supposed gay tryst was the real reason behind the whirlwind pace at which Tom, 43, conducted his public courtship of the Dawson's Creek star. It said Rob's wife Marisol "found her husband in bed with Tom Cruise, causing Cruise's people to shift into high gear."

It also stated: "Mrs. Rob Thomas was bought off for an undetermined sum" and that "Cruise and his handlers set out to immediately find Cruise a girlfriend" in the hope of killing off any subsequent gay rumors.

The unbelievable message went on to claim "second-tier" actresses, including Jessica Alba and Lindsay Lohan, had also been "targeted" by Tom but that the actor was only able to "strike a deal" with Katie Holmes, 26.

The married singer kept quiet for several weeks before finally confirming he had not had sex with the War Of the Worlds star.

Thomas has been surrounded by rumors of bisexuality and admits he has "no problem" being labeled homosexual.

Rob also made fun of Cruise's strict devotion to Scientology, the controversial L. Ron Hubbard religion and said: "I'm more offended by the rumors saying I'm a Scientologist."

Cruise's sister, Lee Anne Devette, who also acts as the star's publicist, did not return calls for comment.
