Kathy Hilton is no stranger to reality TV. Daughter Paris Hilton was one of the reality TV originals, having starred with Nicole Richie on The Simple Life starting back in 2003.

Now there’s some speculation that Kathy Hilton might be making her first foray into starring on reality TV. Rumor has it she’s on tap to replace her younger sister Kyle Richards on The Real Housewives of Beverly Hills.

Kyle and sister Kim Richards have been staples of RHOBH since the show debuted back in 2010, but Kyle Richards has reportedly had enough of reality TV–at least for now.

“Kyle hasn’t been happy for two seasons now,” a source tells Page Six. “She has ruined any chance at a friendship with the cast mates and she isn’t sure she can stomach another season.”

Kyle’s relationship with Kim Richards has been especially strained due to their work on the show. The two engaged in a screaming match during the season five reunion special in April, but they have since been spotted–along with Kathy Hilton–getting along at Kim’s daughter’s wedding earlier in June. Kim Richards is in a 90-day alcohol rehab program. She was arrested for public drunkenness at the Beverly Hills Hilton earlier in 2015. It is expected that in order to maintain her sobriety, Kim Richards won’t return to The Real Housewives of Beverly Hills when filming for the next season begins.

“Both Richards sisters are fed up with the drama of reality TV and want out,” a source says. “Lisa Vanderpump feels the same way.”

TMZ reported last week that RHOBH has given Brandi Glanville her walking papers.

Will Kathy Hilton step up to the plate and join the cast of The Real Housewives of Beverly Hills?

“Kathy’s been approached to join the cast, but is undecided,” a source reports. “She doesn’t know yet if she wants to be part of all the drama.”

Kyle Richards claims the notion of Kathy Hilton signing on to star in RHOBH is nothing but a rumor.

Is Kathy Hilton a good fit for RHOBH, if in fact this rumor proves true? Will Eileen Davidson, Lisa Rinna, Lisa Vanderpump, and the rest of the gang welcome her on board if she accepts the invitation?
