Demi Lovato, Chris Wallace perform in Philly tonight

After axing her Fourth of July Jam performance on the Parkway two weeks ago, Demi Lovato is saying "I want you back" to Philly with a concert at Penn's Landing Wednesday night.

A rep confirmed to Wednesday that the singer will rock out to her hits as part of a free summer music series.

The first of three concerts of Pop-Tarts' Crazy Good Summer was held in Atlanta and featured Hot Chelle Rae and Owl City. The second will take place tonight at 6 p.m. at River Stage (1 Columbus Blvd., Philadelphia, PA 19123). Chris Wallace, of Remember When Push Rewind fame, is also slated to perform.

Unfortunately, all available tickets for this event are long gone.

And marking its timely debut: Lovato's latest music video, "Made in the USA," dropped Wednesday, too. Watch below.
