10 Celebrities Rumored To Be Difficult To Work With

Katherine Heigl's already contentious reputation took a beating earlier this month, thanks to a scathing -- if not entirely new -- report from The Hollywood Reporter that accused the actress of being difficult and "not worth it." Among other things, the article compelled Heigl's "North of Hell" co-star Patrick Wilson to defend her on HuffPost Live: "She showed up, worked her tail off, super funny, super gracious, great to the cast, great to the crew, and was a total pro," he firmly attested, offering, for once, the other side of the story.

But Heigl isn't the only celebrity whose diva reputation precedes her, of course. Check out these other female stars, across all disciplines, rumored to be difficult to work with, from Mischa Barton to Nicki Minaj.
