Country music star Kenny Chesney has denied rumours he split from Renee Zellweger because he is gay. The couple checked the word "fraud" on their legal separation documents when they split, which fuelled rumours about the singer's sexuality. Speaking for the first time about the annulment to US news show 60 MINUTES he says, "The only fraud that was committed was me thinking that I knew what it was like... that I really understood what it was like to be married, and I really didn't. "We thought the least harmful (stated reason) was fraud because it (is) kind of broad... doesn't specify (the reason for the separation). And boy... we were wrong!" Speculation Chesney was gay grew because Zellweger was the one citing fraud as the reason for the split. He says, "Its not true. Period. Maybe I should have come out and said, 'No, I'm not (gay),' but I didn't want to draw any more attention to it. I didn't have to prove to anybody that I wasn't (gay)." But Chesney insists he has no regrets about marrying the Oscar winner: "I loved her... It was real." Zellweger, 37, and Chesney, 38, married just four months after they met in 2005 and split four months later.
