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.
