Actress Sophia Bush is calling on her fans to support a new charity drive to raise funds for a music education organization for kids.
The former One Tree Hill star is backing the Sweat For Change: 30-Day Challenge, which encourages people to work out and raise $10 a day for a month, with all donations benefiting Little Kids Rock, which has a fundraising goal of $100,000 .
To boost the CrowdRise.com effort, Bush has offered up signed T-shirts and a personal phone call in a special sweepstakes.
Rallying support for the cause, Bush writes on Twitter.com, "Just launched Sweat for Change for an awesome charity. First 5 to give at least $26 get a signed CrowdRise tee".
