Arianna Grande

Caught ya!

Pop music "It" girl Ariana Grande planted a wet one on her ex boyfriend, Jai Brooks, backstage at the iHeartRadio Awards in Los Angeles on Thursday. Looks like the former flames have kissed and made up!

Back in October, Jai, who is a member of the Australian YouTube comedy and prank group The Janoskians, said that Ariana was still in a relationship with him when she started seeing The Wanted star Nathan Sykes. Looks like that's all water under the bridge now!

Prior to the smooch, the 20-year-old Nickelodeon star wowed the crowd at the fun-filled awards show held at the Shrine Auditorium. The big-voiced singer sang a pitch-perfect medley of "The Way" and "Problem."

Looks like Ariana was on fire last night!
