Kyle Richards "The Housewives of Beverly Hills" star had been rumored to quit the reality show.
According to TMZ, Rick Hilton said that Richards got pissed off with Bravo TV on airing her family's dirty laundry leading her to quit the reality series.
However, according to some sources, the real score of Richards decision to leave the show was because of her husband Mauricio Umansky. Umansky left Hilton and Hyland and started to compete with Hilton's real estate business.
Umansky's move displeased Hilton couple, which resulted to a feud between the sisters, Kathy Hilton and Richards.
A source told People that the two have not been speaking to each other and have not yet settled their issues up to this day.
Reports also claimed that Richards was not invited to her niece's (Nicky Hilton) London grand wedding. Nicky got married to banking heir James Rothschild in July.
Still Richards made it to the wedding and she posted her 7-year-old daughter's photo who served as the flower girl. The rift between the two remained when Hilton allegedly did not invite Richards' family including her husband and two more daughters.
During one of Richards' interview, she admitted that she was not in good terms with her sister, Kim.
"Kim and I aren't getting along well right now. It's been obviously a difficult time this last year," Richards said. "Things are good. She is good. She is healthy so that always helps our relationship."
Meanwhile, Inquisitr reported that Kim had a tough year in the preceding season of "The Real Housewives of Beverly Hills." She was getting in and out of rehabilitation due to public intoxication which made her relationship with her sister got worse. However, Kim is said to be trying to get her life back on track.
During the holidays, "The Real Housewives of Beverly Hills" families are still not getting along.
