Is Alex Pettyfer A Diva Bitch?

Despite starring roles in three 2011 films, British actor Alex Pettyfer is developing a reputation as a hot young star – but also as a diva who is difficult and demanding.

According to several sources on the set of I Am Number Four, tensions between Pettyfer, 20, and director D.J. Caruso ran so high last summer on the Pennsylvania set that DreamWorks CEO Stacey Snider was forced to intervene. He was spotted at the premiere with his girlfriend and other co-stars.

Insiders say that when Pettyfer, who was being paid in the $250,000 range for the film, heard he was making less than another actor, he demanded to renegotiate his deal. DreamWorks refused, prompting Pettyfer to go into protest mode. As recently as December, he had not cashed a single check for his Number Four work. (He has since cashed checks.)

Pettyfer then switched his agents and his girlfriend, Dianna Agron, soon fired her entire team and signed with his agent.

He’s also been reported to have kept studio heads waiting for hours, asking for outrageous sums of money for upcoming films but some say that it’s worth it.

“Pick your words: ambitious, hungry, cocky, very ahead of himself,” says a producer who has worked with him. “But if he delivers, he’ll be worth it.”
