ROBERT Pattinson and Kristen Stewart are about to get charitable. According to reports, the Twilight stars have been asked to take part in George Clooneys telethon to raise money for Haiti. The Caribbean island is currently recovering from its biggest natural disaster in decades after recently being hit by an earthquake measuring a magnitude of 7. 50,000 people are thought to have been killed. Clooney, 48, is hosting a telethon to raise funds for the people and it is claimed he wants Rob, Kristen and Taylor Lautner to get involved. Theyd jump at the chance to do something to help, said a source close to the trio, although it is not yet known if the actors are available to take part. Meanwhile, golfer Tiger Woods is reportedly set to donate $3 million to the victims fund. SS
