Selena Gomez, the Jonas Brothers Rock ‘Concert for Hope’ (PHOTOS)

It was a night of giving back for Selena Gomez, the Jonas Brothers and Allstar Weekend, as the Disney pop trifecta belted out their greatest hits in the name of charity.

Selena looked pretty (as always) in pink, performing in a cute dress with some cutouts. The Jonas Brothers had their normal cool and casual looks going, with Joe sporting a fancy man scarf while Kevin cranked out some riffs on the guitar in a leather jacket.It was the third annual ‘Concert for Hope’ event, which is aimed at raising money and awareness towards cancer research. Over the first two years, the shows have helped raise nearly $1 million for research, according to the web site.

For Joe Jonas, it had even more significance, as it was the first time he’s taken the stage since his sudden split from girlfriend Ashley Greene. He referenced the scenario on Twitter, saying: “Gonna feel good to be on stage again.”

It was a first for Selena too, as the teen beauty tweeted: “So excited!!!!! performing Who Says for the first time tonight at the Concert for Hope.” Check out the video for “Who Says” below:
