She's a Belieber!

Justin Bieber, 16, may have found his one love in his tour's opening act, Jasmine Villegas, 16.

Though his rep tells Us Weekly they're "not dating," the duo have gotten awfully close -- and were spotted kissing inside a Honda Sept. 9 in Venice, Calif.

"She was supposed to be left off the upcoming Hawaii concerts," says an insider.

"But Justin wanted her there, so he made it happen."
