Singer Lance Bass and actresses Emmanuelle Chriqui and Jenna Dewan-tatum are among the stars who have signed up for a marathon theatre challenge to raise money for charity.
American Pie's Eddie Kaye Thomas, actress Jodie Sweetin and The Simpsons star Yeardley Smith will also take part in Hollywood Rush, which challenges performers to write and stage six 10-minute plays from scratch in a 24-hour period.
Proceeds from the event, to be held on 19 February (12) in Los Angeles, will be donated to The Baby Dragon Fund, which supports recovery programmes for drug addicts.
