Cody Simpson pulls out his guitar to perform at the DoSomething.org and Aeropostale Teens for Jeans Kick-off Party held at Palihouse on Tuesday night (January 10) in West Hollywood, Calif.

Teens For Jeans is a national campaign launched in 2008 by DoSomething.org and Aéropostale which urges teens to help provide the number one item requested by homeless teens at shelters. 2012 marks the 5th Annual Teens For Jeans campaign, which will run from January 16th – February 12th with a goal of collecting one million pairs of jeans.

“It’s always a pleasure doing something for DoSomething.Org or any charitable organization. It’s important to give back. #teensforjeans,” he tweeted.

Cody just turned 15 today! Go give him some Twitter love @CodySimpson.
