Shahs of Sunset's Golnesa "GG" Gharachedaghi has long been open about her collection of knives, but it's not until season 2 that she threatens to use them. In a wild new preview from the Bravo show's new season, GG flips when her costar, Mercedes "MJ" Javid gets a little too close to comfort.

"I would love to cut your face with a knife right now," GG snaps during a fiery spat with MJ. (Watch a clip above)

GG's costar, Reza Farahan, argues that GG's behavior is more out of control than ever. "GG is like a venomous pet snake," he says as GG feuds with a handful of women in the preview clip. "We don't joke about GG and knives. If you look up GG in the dictionary, there's a picture of that bitch with a machete! Take an unstable person and a knife? Yeah."

GG isn't the only Shahs of Sunset character making an impression when season 2 kicks off Dec. 2. Dubbing himself "the Persian daddy," Mike Shouhed is again on the hunt for love, charming every girl he meets. But, as the reality star explains, he's anxious to put his bachelorhood behind him and settle down with The One. "I'm a different guy than last year. I've evolved -- I've grown up," Shouhed says.
