With His Opening Act
The chick playing tonsil hockey with The Biebs is 16-year-old Jasmine Villegas -- who also happens to be the opening act on Bieber's concert tour.
The photos were taken on Thursday, September 9 in Venice, CA by some Canadian tourist who just happened to notice his country's most famous pop star in the midst of a make-out session with the luckiest teenage girl on the planet.
The two had been rumored to be dating ... but they insisted they were just "really cool friends."
