LOS ANGELES (Reuters) - Pop princess Britney Spears (news) has admitted that she had sex with former boyfriend Justin Timberlake (news) despite once vowing to remain a virgin until she wed.
In the upcoming issue of W magazine, Spears details her relationship with Timberlake, the most-watched music industry romance since Courtney Love (news) and Kurt Cobain.
"The most painful thing I have ever experienced was that breakup," Spears told W. "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."
The 21-year-old Spears, whose stratospheric rise from Mouseketeer to pop megastar mirrored Timberlake's success, revealed that she had sex with the 'N Sync (news - web sites) boy band singer because she believed they would marry someday.
"I've only slept with one person my whole life," she said. "It was two years into my relationship with Justin, and I thought he was the one. But I was wrong!"
