Ariana Grande was all smiles, spreading holiday cheer at Jingle Ball 2014 in Los Angeles on Friday night. Held at Staples Center, the now Grammy-nominated pop diva called on a few big stars to join her on stage. The Weeknd was up first, as the duo performed their My Everything duet “Love Me Harder.” Jessie J, who was a performer earlier in the night, rocked her smash-hit with Grande “Bang Bang.”

Just moments after performing at Power 106’s Cali Christmas concert on the other side of town at The Forum in Inglewood, Big Sean joined his girlfriend on stage to perform “Best Mistake.” The cute couple were cozy on stage, at one point in the arms of each other before Big Sean kissed Ariana on the cheek before exiting.
