Lite Rock singer Kelly Clarkson may have multiplatinum albums, a couple of Grammy awards and a die-hard fan base, but there is something she does not have - a boyfriend! In an interview with USA Today, the 29 year-old original American Idol winner reveals she's never been in love.  "I've never experienced certain things, and I think that's because I have this side of me that is shut off," Clarkson says. "Because I haven't found anybody yet to open to that I feel like, 'OK, you're worth breaking down that wall for.'
