"Magic Mike" actress Olivia Munn is said to be quite a tantrum queen on the set of TV show "The Newsroom".
Her behaviour is said to have been troubling her co-stars and colleagues.
"Olivia acts like she runs the show. She bosses everyone around, whines about the scripts and tells the wardrobe staff they can't do anything right," showbizspy.com quoted a source as saying.
"By the end of each shoot, people aren't even speaking to her...if she keeps this up, she won't be around for long," the source added.
The show airs on HBO.
