Kelly Clarkson is used to hearing rumors she's a lesbian by now, but the singer continues to insist she's only into men.

"I get hit on by the hottest girls ever. Oh, my God, if I were a lesbian, I would be so in luck. But it's just not my thing. I've always batted for the boys' team," the first-season American Idol winner told Cosmopolitan magazine.

"People think, 'Oh, she's been single for too long.' That's kind of an insult to the gay community. Being single doesn't mean you're gay. But I'm never insulted by it, obviously."

But now, Clarkson is engaged to Brandon Blackstock and over the moon about finding her perfect guy. She even admitted she's "freaked out" about how happy she's been, thinking it may be too good to be true.

"Six years I was single before this," she told Cosmo. "I've never been truly loved like I am right now."

Clarkson's engagement, however, doesn't stop guys from hitting on her -- just like it hasn't stopped some women.

"But usually the guys who hit on me are tools. It's the ones that don't hit on you that make you like, 'Why didn't you ask me out?' It's like American Idol auditions: The guys who are the most confident are the horrible ones, and the ones who are good have no confidence at all," the former Duets star explained.
