Megan Fox has had another bust-up with boyfriend Brian Austin Green over her film flirting. The Transformers star, 23, has apparently angered her beau with her flirtatious ways with co-stars — and not all of them male.

“Brian is aware that Megan is a very sexual girl and a very attractive one at that,” reports an insider. “With both of them so busy now, it’s rare they are together and that isn’t helped with the way Megan is with the people she works with. 

“She is a very sweet girl but she’s a terrible flirt. It’s not that Brian doesn’t trust her but he feels it’s putting the wrong messages out about them as a couple, and he wants it to stop.”
