Kim and Kyle Richards, the celebrity sisters who star in Real Housewives of Beverly Hills are reportedly not speaking to each other - again!!

"Kyle Richards has been sincerely concerned for her sister Kim Richards that she has not been in a good place, so a couple of days ago she decided to reach out," an insider told HollywoodLife.

But Kim was not happy with Kyle's reaching out:

 "The two sat down and had a conversation and Kyle is upset and frustrated because Kim did not take well to it," the source continued.

"[Kim] felt Kyle's words came out harsh and that Kyle was overstepping her boundaries and [was] out of line. But Kyle felt it was her duty as her sister to let her know that she's here to help and [that she's] concerned."

The two then had a "heated" discussion and are not on good terms right now.

When it comes to Kim's health and sobriety, Kyle's touch and delivery has often been extremely harsh in front of the cameras. Kyle regularly sides with the other ladies over her biological sister.
