Jonas Brothers, Selena Gomez and Others at Concert for Hope

Last Sunday evening, March 20, Los Angeles hosted the third annual Concert for Hope at the Gibson Amphitheatre to raise funds to benefit lifesaving cancer research at the City of Hope, one of the leading cancer research and treatment centres in the US.

The headline acts were the Jonas Brothers, Selena Gomez and The Scene, and Allstar Weekend.

The Jonas Brothers walked down the red carpet dressed casually in matching jeans, T-shirts and jackets. Selena Gomez graced the welcome carpet dressed in a short-sleeved top and red scarf. Her excitement about the concert was infectious as noted by her Tweet prior to arrival, "So excited!!!!! performing Who Says for the first time tonight at the Concert for Hope."

Numerous other acts on the night included: all-girl group Cherri Bomb, actress Anna Maria Perez de Tagle from "Camp Rock", host from Radio Disney Jake Whetter, and YouTube star Christina Grimmie.

Selena Gomez and The Scene performed their latest single 'Who Says', while the Jonas boys sang a number of their hits including 'Lovebug' and 'Paranoid'. Nick Jonas also made 13 year old Rebecca Black proud by singing a cover version of her recently released song 'Friday'

Following the concert, the Jonas's sent a message to all their fans via Facebook in appreciation of their support. The note included: "Today we just played at The Gibson Ampitheater for an incredible cause with some incredible people."

The amount of money raised so far has not yet been determined, but from all reports, it was a huge success.
