The heat is on after a new U.K. poster for the upcoming buddy-cop comedy starring Sandra Bullock and Melissa McCarthy hit the web.

McCarthy fans are up in arms about a supposedly digitally retouched poster of The Heat that appears to have shaved inches from the off the funny lady's chin and neck. 

Posters for both the U.S. and U.K. versions feature the actresses against a pink/red background, but the U.K. version is far more digitally altered. In it, McCarthy looks to have had her neck and face slimmed down thanks to Photoshop -- carving off what some critics estimate to be up to 30 pounds. 

British entertainment blog The Shiznit created a rollover image of the poster, showcasing the difference between McCarthy's poster face and what they believe her actual, undoctored face would look like on the same shot.

"Are they trying to pretend it's not her?" the blogger muses. "Surely the whole point of The Heat's dynamic in the first place is that Sandra Bullock's character is skinny and prissy and uptight and Melissa McCarthy's character is bigger and bolshier and her diametric opposite? I'm flabbergasted at this flabby-blasting." 

This isn't the first time McCarthy's image has undergone the "photoshop diet," as The Hollywood Reporter noted; for Bridesmaids she was given a slimmed-down look as well. 

Calling in to VH1's The Gossip Table on Monday to address the controversy, Rosie O'Donnell recalled her own experiences on 1996's Beautiful Girls.

"It was an ensemble piece so there were many, many actors in it, and you never got to work with everyone," she said. "When the poster came out, it was sent to my office and I looked at the poster and I said, 'Oh, I didn't know Courteney Cox is in this."
