Brad Pitt, George Clooney's friendship at end?

Brad Pitt and George Clooney’s friendship is apparently cooling off.

The mole added: "George is happy that Brad's divorce drama is mostly behind him, but they're not exactly popping champagne corks together! Nothing stays the same in Hollywood so why should this particular relationship be any different?

"Things ebb and flow and people come and go: wives, husbands and even best friends. They are not war, just at arm's length

“Sure they were once the dynamic duo of Hollywood's elite, and now they are giving fans the ultimate plot twist: the bromance is on ice!,” declared the source.

Brad and George put their friendship and playful camaraderie on display during the filming and promotion of their movie Wolfs. Unfortunately for the duo, the movie didn’t receive praise from critics.

“They were Known for their on-screen chemistry and playful off-screen camaraderie, the two megastars have been noticeably absent from each other's lives lately," revealed the tipster.

Wolfs’ dismal performance and scathing reviews have apparently given the duo a push in different directions.

"George is starting to feel like every time he tries to do something with Brad, it blows up in his face. And Brad is getting tired of being his buddy's whipping boy," noted the mole.
