The upcoming reunion for Season 11 of The Real Housewives of Beverly Hills was the first time Kathy Hilton joined the cast and Andy Cohen for a season-ending sit-down. But she definitely came prepared in true Real Housewives fashion.

Kathy, along with sister Kyle Richards, answered a round of "spooky questions" during her appearance on Watch What Happens Live with Andy Cohen on September 29, including one query about the RHOBH reunion. "Kathy, how frightened were you going into your first reunion, and did you come out unscathed?" Andy asked.

"I wasn't frightened," Kathy replied. "It was very interesting. It was wild. It was wild."

Andy then noted that Kathy "brought a list of receipts" with her, which, he said, "I really enjoyed."

Kathy confirmed that she did, in fact, bring receipts to the RHOBH Season 11 reunion, and she went on to reveal more about the proof she provided. You can watch Kathy dish about it all, above.

That wasn't Kathy's only reunion moment that seemed to leave an impression on Andy. He previously shared one of the revelations about Kathy that came out during the taping. "She told me at the reunion that she and [her] husband [Rick Hilton] and Paris and Nicky sit around the living room eating off of trays," Andy said on WWHL on September 16, referencing Kathy and Kyle's unforgettable snacktime earlier this season. "That's how they eat their meals."

Andy spilled even more tea about the RHOBH reunion during a recent appearance on The Tonight Show Starring Jimmy Fallon in which he revealed that it will be four parts. "It's that juicy," Andy said. "It's incredible. We don't leave any content on the floor."

Earlier this month, Andy let fans in on his prep and how he was feeling heading into "the most highly anticipated reunion in years." Lisa Rinna and Sutton Stracke also gave some major teases of the reunion during their recent visits to the Bravo Clubhouse.
