Kathy Hilton and Paris Hilton Spill Hilton-Richards Family Secrets

There's no denying that Kathy Hilton and Paris Hilton have lots to share when it comes to their large and ever-expanding family. In addition to opening up about Nicky Hilton Rothschild's recent pregnancy announcement and dishing on celebs who attended Paris's extravagant wedding, The Real Housewives of Beverly Hills mom and her eldest daughter recently spilled some juicy details about their family during their January 26 appearance on Watch What Happens Live with Andy Cohen.

During a game of "To Tell the Tooth" (clip above) host Andy Cohen asked Kathy to answer "a mouthful of shady questions" about the people in her life, including her sister, RHOBH's Kyle Richards. When asked which of the Beverly Hills Housewives did Kyle complain about the most, Kathy answered, "Honestly, she doesn't."

When it came to Kyle's RHOBH Season 11 reunion look, Kathy had this to say about it: "I would say that she looked adorable." As for her daughter, Kathy also opened up about one thing Paris has done in public that has embarrassed Kathy. The RHOBH mom told Andy, "I think when she walks out on a talk show, because she's shy, she acts like it's a red carpet."

Speaking of Paris, Andy wanted to see how much the socialite was in sync with her mom during a game of "The BFF Test" (clip below) in which he asked a series of questions to see if their answers matched. The mother-daughter duo did not see eye-to-eye on the question asking about the more iconic catchphrase, "That's Hot" versus "Who is Hunky Dory?" Kathy, of course, went with her very own memorable line.
