The "Real Housewives of Beverly Hills" meeting this season was obviously among the most sentimental for celebrity Kyle Richards, who explains to media it was a "truly tough time" due to unrest with sister Kathy Hilton.

Throughout a drunken rant in Aspen, Lisa Rinna alleged Hilton of making several pretty nasty comments regarding her sister and the other cast members.

Whereas Kathy apologised to her sister and Kyle appeared to be prepared to move on, Rinna and Erika Jayne refused to let go of the subject – and it appears that emotions flared during the meeting.

Kyle spoke with media after a teaser for the reunion taunted some harrowing scenes for her – and even in media stories that she and Kathy are "hardly on speaking terms."

Richards discussed how challenging she found it to film the three-part special as well as the "frustrating" state of affairs with her sister.

"I came to know it would be tough going in, but I don't assume folks realize how much my relatives issues impact me. "And I'm an empathetic person," she said while promoting her character in "Halloween Ends.""

"So to retain that in for such a long time and to see it all come to a head at the reunion, I just was... I was a chaos."

"It was an extremely tough time, without a doubt," Richards added. "We arrived at 6 a.m., and I left at 11:30 at night."
