They haven't even started doing a scene together but "Scream Queens" cast Emma Roberts and Ariana Grande are reportedly already butting heads.
According to Hollywood Life, Roberts reportedly heard a rumor about the "Problem" singer that made her very upset. She was so stressed out that even her beau, Evan Peters, allegedly couldn't pacify her.
"Emma heard that Ariana doesn't want anyone to have cell phones on set and the rumor really upset her," the gossip site's supposed source reported.
"She ended up losing it during a rehearsal, while heatedly telling a producer how upset she was," the insider added. "Her fiance, Evan Peters, was there and had to try and calm her down, but she ended up storming off set."
The 24-year-old actress has worked on two seasons of "American Horror Story" and will portray a sorority Queen Bee in Ryan Murphy's new TV creation.
The "Scream Queens" cast will also be joined by other actresses who have worked with Murphy in the past.
On the other hand, this will be Ariana Grande's first time working with the popular series creator. Despite being a Murphy-show newbie, the 21-year-old singer has appeared in a couple of successful Nickelodeon shows.
According to The Gossip Table (via VH1), however, the whole thing allegedly turned into a "catfight" with Roberts "screaming to Murphy about how upset she was" about the Grammy-nominated singer's diva behavior.
FOX and Grande's representatives promptly issued a statement regarding the issue.
"Ariana Grande is currently on tour and has yet to hit the stages of 'Scream Queens.' These rumors are false and we look forward to working with her," the network declared.
The "Break Free" singer's representative backed up FOX' statement, confirming that she is still indeed on her tour.
Other "Scream Queens" cast members include Jamie Lee Curtis, Lea Michele, Oliver Hudson, Keke Palmer, Abigail Breslin, Nick Jonas and more.
