'Bad Girls Club' Arrested -- Judi Jackson Threatens Cop ... 'I'll Sue Your F***ot Ass'

Former "Bad Girls Club" star Judi Jackson got wasted, lost her phone, fought her friend, and then, just for good measure ... hurled a homophobic slur at the cop who was arresting her.

TMZ obtained video of Judi arguing with a male friend in a gas station parking lot outside Chicago Wednesday night -- and you can see her smash his phone and then yell, "Bitch, find my phone."

The friend wasn't having it, and called police to deal with Judi ... not that they had it any easier. According to the police report, she hit an officer in the chest with an open palm. Once they got her in the car ... cops say she screamed, "You don't know who I am, I am going to sue your fa**ot ass."

In addition to the phone, police say she broke her friend's car key and his rear view mirror.

Jackson tells us she pushed the officer in self defense. She claims he threw her onto the patrol car while cuffing her.

She can tell that to the judge ... Jackson was booked for resiting arrest, battery, and damaging property.
