Chris Brown, Rihanna Break Up Turned B**ch Mode? Employees Dish About Diva Behavior

According to Rihanna's "Diamonds World Tour" entourage, the singer hasn't been the nicest celebrity to work with.

Sources that worked close with the "Diamonds" singer told Star Magazine, Rihanna was impossible to work with ever since she broke up with Chris Brown, "We're always sent on some errand to the middle of nowhere just to find something trivial, like the 'right' ice bucket or color notepad," the source explained to Star magazine, "Rihanna has never been easy to work for, but since she and Chris Brown broke up, she's been beyond horrible."

The source claims that Rihanna recalled an incident when the singer went into diva mode, "Rihanna wouldn't go onstage until she got carne asada, but by the time he returned - from an hour away - the food was cold. Rihanna threw a fit, like it was his fault!" the source continued, "She's in a bad mood 24/7 and takes it out on everyone who works for her," the source said adding, "She's so rude, always snapping at people, and she's a nightmare to be around when she's hung over. I can't even remember the last time she said 'please' or 'thank you."

Hmmm, we do see Rihanna's mood swings on Instagram and Twitter, but maybe it's the lack of sleep?
