Lisa Vanderpump was smart enough to stay away from the 'Real Housewives of Beverly Hills' reunion, but Camille Grammer reportedly had a "full breakdown" when she turned up to face the ladies.

“At one point, Camille ended up walking off the stage and had a full breakdown,” one insider told US Magazine. Camille reportedly got into it with newcomer Denise Richards.

During the season, Camille was called out for being two-faced. Camille on several occasions was sweet and loving to a few of the ladies' faces before bitching about them behind their backs - or in her shady confessionals.

Camille addressed the reunion via her Twitter account:

“I showed up in good faith for #RHOBH reunion but I shouldn’t have gone... Hindsight is 20/20," she tweeted a day after filming.

“They have been talking behind my back the whole time,” she tweeted. “The Hypocrisy of it all.”

This reunion is going to be a fiery one!
