"Lisa, Kim and Kyle are all hideously wealthy," a source told RadarOnline. "They live in these amazing houses, drive beautiful cars, live these fabulous lives and spend money like it's going out of fashion."
While Bravo has yet to formally announce plans for a Beverly Hills edition -- which would represent the sixth The Real Housewivesinstallment -- reports of the potential project had surfaced after casting notices seeking "outgoing, exciting, strong, focused women who reside in and around the Beverly Hills area that want to share their lives" were released last May.
"The casting is meant to still be a secret but there's no such thing when it comes to Lisa! She's been sworn to secrecy about her involvement but has been telling anyone and everyone that will listen! When it comes to Lisa 'loose lips' is definitely a saying that springs to mind!" the source told RadarOnline.
"Actually, it could be applied to all three of them! They all love to gossip and there's a real rivalry between them, even though they socialize together and are friends."
In addition, the source promised "a fair share of drama, cat fights and bitchiness" on the reported series.
While Paris has starred on The Simple Life and Paris Hilton's My New BFF, Kathy starred in I Want to be a Hilton -- a reality competition series that aired on NBC in Summer 2005 and featured contestants vying for the chance to live like a Hilton.
