“Diva” Bradley Cooper And Fearful Zach Galifianakis Not Getting Along In Rio?

The stars of "Hangover 3" disappointed fans and press in Brazil this week, when Zach Galifianakis was too afraid of heights to attend the conference and Bradley Cooper was unfriendly and deemed a "diva."

Galifianakis, 42, pulled out of the press conference last minute when he realized there was no other way to attend the event except to ride up to Morro da Urca in Rio de Janeiro by a 220 meter cable car ascent, The Daily mail reports. His fear of heights got the better of him.

"The only way to get up there was by cable car. Zach was too afraid to ride up," a source told the New York Post.

The rest of the cast, which includes Bradley Cooper, Ed Helms, Heather Graham, and Ken Jeong, all made it up to the peak near Brazil's famous Sugarloaf Mountain. But it was not smooth sailing from there.

Bradley Cooper was standoffish during the press conference. Glamurama.com, a local media outlet, said: "Bradley Cooper, even [though he was] quite late, was not even a little friendly nor receptive to questions from reporters." 

Glamurama.com stated the actors were three hours late, and called Cooper a "diva." Bradley ignored fans who had waited for hours to see the stars.

The outlet also claims that there was some problems amongst the actors. Management suddenly stopped photographers from taking pictures at the promotional event, The Daily Mail reports.

Glamurama.com said: "The gossip behind the scenes is that there was a disagreement between the team on Tuesday night at the hotel."

This is perhaps another reason Galifianakis didn't feel particularly inclined to ride in the cable car with Cooper to the conference.

However, it doesn't seem like the argument is too serious. The Wolfpack was spotted at the beach in Rio on Wednesday, and all were getting along just fine as they hit the waves. Let's just hope Cooper and Galifianakis can make up soon.
