Nashville’s golden girl Carrie Underwood is one of the hottest country acts around, and yet despite her undisputed beauty and talent, the former American Idol can’t seem to find love.

At this CMA Music Festival, there was buzz mounting that Carrie had a new man, 26-year-old Ryan O’Nan, whom she met through his employer and Carrie’s tourmate, Keith Urban.

The pair had been on a handful of dates, including down-home parties in Nashville and outings at the Four Seasons and Mix nightclub in Las Vegas last May. Following weeks of whispers, the duo was rumored to finally be going public at the festival, but when the shy Southern gal sadly showed up solo for the big ceremony on June 6, it seemed that love had once again gone wrong for the American Idol.

So just what caused the relationship to flame out so quickly — her success? "I scare guys off," Carrie, who previously dated Dallas Cowboys quarterback Tony Romo, 28, and Gossip Girl hunk Chace Crawford, 22, tells OK!. "I don’t really need any help."

While the blonde beauty may blame herself for her bad luck with men, it appears that Ryan’s rumored roving eye may have played a role in her most recent split.

"Ryan is a really fun, nice guy, and he and Carrie never run out of things to talk about, but he has a reputation as a player, and she jokes that he’s bad news," a source close to the 25-year-old star tells OK!.
