Kathy Hilton Has Meltdown During 'RHOBH' Aspen Cast Trip, Got Into Shouting Match With Nightclub Employee Over Michael Jackson

Sources with direct knowledge of the situation tell us that one night after Bravo cameras stopped rolling, Kathy and the cast continued partying at Caribou Club – a prestigious, members-only lounge that we're told Hilton has frequented over the years.

We're told she was jet-lagged and exhausted and just wanted to hear the DJ play one specific song – Michael Jackson's 1982 hit, Billie Jean – however, there was some sort of screen dividing the headphone-wearing man mixing the music from the rest of the crowd, so she asked a nearby Caribou employee to help her relay the message.

We're told said staffer was extremely rude to Kathy when she made her request, apparently asking her where she was from. When she answered him, he allegedly told her to "go back to L.A." The remark sent Kathy over the edge, and a heated exchange of words ensued.

One eyewitness claims Hilton shouted that they were looking at "white privilege" and needed to back off; however, her representatives emphatically deny she said anything of the sort or used any obscene language, as it's "not in her vocabulary."

Meanwhile, Bravo representatives tell us the story is "news" to them, given that it was not captured during filming.

We're told a distraught Kathy was then accompanied out of the venue by Lisa Rinna and that the two rode in a sprinter van back to where the group was staying.
