Russell Crowe is taking a chill pill. Just days after reportedly being involved in a London restaurant brawl, the Oscar champ says that he has been under a "massive level of stress" and is heading back to Australia to be with his father and girlfriend. What's more, he announced that his band, 30 Odd Foot of Grunts, were canceling their upcoming U.S. tour. In a message posted on the group's website, Crowe cited his father's upcoming surgery for carpal tunnel syndrome as a factor in his decision to return home.
