RHOBH Reunion: Kathy Hilton Calls Lisa Rinna the 'Biggest Bully in Hollywood' as Kyle Richards Pleads to Leave

"You are the worst bully in Hollywood and everyone knows it," Kathy told a surprised Lisa Rinna on Wednesday's show, listing all the ladies she's flown with.

Season 12 ended dramatically, and teasers revealed what occurred when Kathy, 63, joined the gang.

The ladies and presenter Andy Cohen discussed the season at the Beverly Hills Hotel, and it got hot.

Kathy joined halfway, while Diana Jenkins joined remotely due to illness.

After the reunion recording, Kyle Richards begged to be excused from a toast.

Lisa, 59, was soon in trouble for refusing to apologise and move on.
