Watch Nick Jonas Perform "Jealous" At Q102's Jingle Ball 2014

Nick Jonas has had one helluva year, and he's topping it off with a series of performances at iHeartRadio's Jingle Ball concerts all over the country, including at last night's Q102 version in Philly. Even after admitting that he's shed his purity ring and is no longer a virgin, his career is doing just fine!

Nick walked the red carpet at the event (unfortunately his hottie GF, Olivia Culpo, sat this one out), and later treated the crowd to a live performance of his hit single, "Jealous." Watch the video above to see Nick at Jingle Ball!
