Clarkson said she's "never insulted" by the rumor.
"I mean, 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," she said.
"[U]sually the guys who hit on me are tools ...," Clarkson added. "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."
