Actress Sophia Bush is calling on her fans to support a new charity drive to raise funds for a music education organisation 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 (£6.25) a day for a month, with all donations benefiting Little Kids Rock, which has a fundraising goal of $100,000 (£62,500).

To boost the 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, "Just launched Sweat for Change for an awesome charity. First 5 to give at least $26 get a signed CrowdRise tee".
