After wrapping up Season 12 of "The Real Housewives of Beverly Hills" filming,

Kyle Richards grew distant from Lisa Rinna after the former model made derogatory remarks about the actress' half-sister, Kathy Hilton.

Richards exclusively told Page Six Tuesday night while hosting a music event to raise awareness and money for the National Alliance on Mental Illness (NAMI).

"Uh, well, we had sort of a falling out last season with what...

...2happened with my sister, so obviously, that changed a lot of things," Richards said.

Richards continued, mentioning that she "reached out" as soon as she "found out" about Rinna's departure from the reality series.

"I haven't seen her, but we have sent each other text messages and DMs," Richards said.
