Nick Jonas is proving once again that he's a die-hard Lovatic!
Just days before debuting his new single "Levels," the former Jonas Brothers member kicked off the weekend by performing at Time Warner Cable and Lifebeat's MTV Video Music Awards concert in Los Angeles.
Showing off his biceps in a tight black T-shirt with dark jeans, Jonas got the crowd pumped with renditions of "Chains," "Jealous" and other hits from his self-titled album.
Once Demi Lovato took to the stage, however, Jonas just had to stick around and sing some of her songs backstage. The results are pretty priceless.
