Kenny Chesney has finally broken his silence on why his ex-wife, Renee Zellweger, cited "fraud" when she filed for divorce in 2005 - it was the only way the couple could get the marriage officially annulled.

The country singer has spent the past four years dismissing suggestions Zellweger discovered he was gay - hence the "fraud".

And now he reveals the former pair had little choice but to end the marriage with a bit of confusion.

Do you think Kenny Chesney's Gay?

Yes, Definitely

Maybe

No Way

Who Cares?

Getting poll results. Please wait...

He tells Playboy magazine, "I talked to my attorney and her attorney. In order for us to get an annulment, the legal papers could claim either physical abuse, which wasn't true, or mental abuse, which wasn't true. The best thing we could put in there was fraud. So I said, 'All right, do it. Whatever.'"

But Chesney had no idea one word would cause him so much grief as the media speculated about what caused the break-up, four months after the couple wed.

He adds, "That is the most unbelievable thing in the world - 'Because Renee cited fraud, Kenny's got to be gay.' What guy who loves girls wouldn't be angry about that s---? I didn't sign up for that. I've got a long line of girls who could testify that I am not gay."

And, in a bid to make his point, Chesney admits he was quite the ladies man at college, and had bedded "over 100" girls by 2001 - and has continued to have "a good time" ever since.
