Britney Spears and Justin Timberlake were lovers, Britney admits:

After years of saying she'd wait until she was married to lose her virginity, Britney Spears is acknowledging that she had sex with her ex-boyfriend, Justin Timberlake.

"I've only slept with one person my whole life," the pop star tells W magazine for its August issue.

"It was two years into my relationship with Justin, and I thought he was the one," she pauses, then adds, "But I was wrong! I didn't think he was gonna go on Barbara Walters and sell me out."

Spears, 21, and Timberlake, the 22-year-old 'N Sync singer, met as kids while performing on TV's "The Mickey Mouse Club." They were pop's high-profile power couple for three years before breaking up in spring 2002.

...."The most painful thing I've ever experienced was that breakup," Spears says. "We were together so long and I had this vision. You think you're going to spend the rest of your life together. Where I come from, the woman is the homemaker, and that's how I was brought up - you cook for your kids. But now I realize I need my single time." [AP]
