Demi Lovato & Jonas Brothers: Walmart Mates

Gearing up for the premiere of “Camp Rock 2: The Final Jam” later this week, Demi Lovato and the Jonas Brothers were spotted doing some promotional duties yesterday (September 1).

The “Sonny with a Chance” babe and the “Burnin Up” rockers looked to be in good spirits as they posed for pictures at the Wal-Mart in Rochester Hills, Michigan.

Of course, Demi and the boys also signed plenty of autographs for their eager fans like the gracious celebrities that they are.

And later in the evening they all took the stage at the Palace of Auburn Hills for an amazing show together.
