Brad Pitt and Angelina Jolie have tried to kill rumours their relationship is on the rocks by partying together at a Chicago nightclub. In recent weeks gossips have revelled in reports Hollywood's hottest pair is close to splitting, three years after they met on the set of movie Mr and Mrs Smith. Jolie has even been spotted viewing a California villa on her own. But the couple held hands early on Monday (13Aug07) as they left a night-time hotspot in the Windy City, where Jolie is shooting a new movie Wanted.
