Demi Lovato and Nick Jonas's Future Now Tour has officially begun! The 23-year-old former Disney's Camp Rock stars kicked off their joint summer tour at the Philips Arena in Atlanta on Wednesday night. The duo's killer show included an appearance by rapper T.I. who chimed in on "Live Your Life" with Lovato and "Whatever You Like" with Jonas, who opted to belt out his hits wearing Dsquared2 denim and a graphic tee.
