REESE WITHERSPOON and her ex-boyfriend JAKE GYLLENHAAL are set to reunite to take part in a star-studded TV telethon to raise money for the Stand Up To Cancer campaign.

The actors, who broke off their relationship last year (09), are among a number of big names who have signed up to join the charity fundraiser, including The Big C star Laura Linney, cancer survivor Christina Applegate and Terrence Howard.

The Stand Up To Cancer telethon will see celebrities manning the phones to take donations from the public during an entertainment special, with performances from Stevie Wonder, Queen Latifah, and Martina MCBride.

The show will be broadcast in America on 10 September (10).
