"I've never been called a diva in my life - I'm a complete team player just ask my friends! #girlsgirl," she recently tweeted. "I think the news outlets should ask people that have actually worked with me if I'm a diva @LeezaGibbons @nbc @realDonaldTrump."
ET confirmed last week that Brandi will not return as a full-time RHOBH cast member next season. According to People, her less-than-stellar attitude was a primary reason.
"Brandi got too big for her britches. She was a diva, and it came around to bite her," a source tells the magazine. "By the end, she couldn't get along with anyone, and no one wanted to shoot with her."
Brandi also openly fought with her co-stars Kyle Richards, Lisa Vanderpump, Eileen Davidson and Lisa Rinna during season five.
Bravo has yet to officially comment on any casting decisions for season six. But ET confirmed earlier this month that Kim Richards, 50, will also not be returning next season following her recent return to rehab.
