Cami, who is the ex-fiancée of TOWIE star Kirk Norcross, made the disturbing comment during a pre-recorded interview on Celebrity Big Brother's Bit On The Side.
The American fetish model was recalling a childhood trip to Disney World in Florida and explained she threatened to "kill" a man who had told her mother to be quiet.
Cami said: "My name is Cami Li and I am a big b*tch. When I was 13 years old we were at Disney World and, like, some guy told my mum to shut up.
"The next thing you know, I was grabbing him by the neck, telling him I was going to kill him."
Laughing, she then added: "So..I would cut a b*tch if anyone f***ed with my family." Err...nice.
Although the new series of CBB only launched last night (7 January), Cami has already kicked things off by slating her ex Kirk, who she dated for six months in 2013.
In another pre-recorded interview, Cami branded Kirk a "little s**t", adding: "It was a whirlwind f***ing nightmare. He is going to f***ing hate me..."
Kirk has logged into Twitter since Cami's appearance on the C5 show, however he has not made any comments about his ex.
The couple dated from June until November 2013 and even got engaged before their bitter split.
