Kim Kardashian can't help that she's man bait.
But on Sunday's episode of Kourtney and Kim Take New York, the reality star, 30, takes a picture with a male fan -- then gets attacked by his girlfriend, who accuses her of getting too close and calls her "a whore."
Explains Kim in the video above, "I don't know what she's thinking, but she just starts cussing me out."
And though the star was out with sisters Kourtney, 31, and Khloe, 26, at NYC's Juliet Supper Club, it was Kourtney's boyfriend Scott Disick who came to her rescue.
"The last thing I want is confrontation. but it seems like Kim needs my help," Disick explains. "I feel like I've got to do something. I think of Kim as a sister and the truth is i can't let this happen without me stepping in."
Unfortunately, when he does, he escalates the argument to a full-blown brawl as the guy throws Disick's handkerchief in his face and his gal splashes Kim with her drink.
Kourtney, pissed that her guy is starting a fight, urges the girls to leave without him and in a shocking twist, Khloe -- who famously referred to Disick as "Douche Lord" -- rushes to his defense.
"We should turn around," she urges, while calling Disick up to find him. "I don't think we should leave him. Like he was protecting Kimberly."
But after living through her man's violent outburts while filming in Miami, Kourtney's not buying it.
Says the mom of Mason, 13 months, "There was a fight and Scott was involved and there's nothing he can say that will make me feel okay about this." Kourtney and Kim Take New York airs Sunday at 10 p.m. (EST) on E!
