Brad Pitt & George Clooney
Clooney has high praise for his longtime pal Pitt. "He's bigger than me, bigger than [Clooney's basketball buddy Leo] DiCaprio. And I really admire how he deals with that. It's not easy for him," Clooney -- who loves to playfully pull pranks on his BFF -- has said. "But he tries to be the most honest version of Brad Pitt that he can be."
