Jonas Brothers: We Are All Virgins
The Jonas Brothers have vowed to abstain from sex until marriage.
The rings are "just one of our ways of kind of like being different than everybody else out there," Nick says. "I got mine made at Disney World," Nick, 15 adds. "It's pretty awesome."
Oldest brother Kevin, 20, has a ring from Tiffany's.
"It's pretty rock and roll," Kevin tells the magazine. "It's getting banged up a little bit because of the guitar."
Though Nick tells Details that he loves the trio's fans -- the "screaming girls are awesome," he says -- the brothers have told Usmagazine.com they enjoy being single.
