Earlier this month, rumors of a cast shakedown for "The Real Housewives of Beverly Hills" began circulating and it was reported that Kathy Hilton is in line to replace her sister Kim Richards on the hit Bravo franchise. But on Saturday, Kyle Richards nipped the rumors in the bud when she spoke with Access Hollywood at a fundraising tea party for The Charlotte and Gwenyth Gray Foundation to Cure Batten Disease in Brentwood. 

When Kyle was asked about the casting rumors about her other sister, the reality star said, "No! That's a rumor! The lies are crazy!" 

Earlier this month, Kathy's daughter Nicky Hilton also denied the rumors, saying that the speculation about her mother joining the show is nothing new as rumors of Kathy joining "RHOBH" have been around before.

During her interview, Kyle went on to say that she has heard various rumors so far, not only about Kathy, but also about her. She said, "I've heard that my sister is joining, I've heard I was fired and begging for my job, I heard somebody else is joining. All lies! Not true." 

The 46-year old said that she has no idea how the rumors started, exclaiming, "They say, 'Where there's smoke, there's fire.' There's no smoke even. There's nothing!" 

When asked whether she would be returning to the show, Kyle said that she couldn't say too much but did reveal that there will be "some big changes" when the reality series comes back for its sixth season. 

Kyle also gave an update about Kim and said that her sister is "doing better" and is "doing what she needs to be doing to get healthy." E! News recently reported that Kim has sought treatment at rehab after she was arrested for public intoxication in which she allegedly attacked a police officer.
