VIDEO : Brad Pitt Takes Chris Cornell's Kids To Universal Studios Hollywood

Brad Pitt, who was good friends with the late musician, was recently spotted at Universal Studios Hollywood by other parkgoers with Cornell's children, 12-year-old Tori and 11-year-old Christopher. The trio sipped on butterbeer from The Wizarding World of Harry Potter and were also spotted walking around Simpsons Land. "Brad and Chris were very close," a source tells ET of the outing. "Brad wanted to be supportive of [Cornell's wife] Vicky and the kids." "He looked really happy and was acting so kindly toward the kids, going on rides and strolling around like nothing was too much trouble," an eyewitness said.
