Lisa Rinna has had many a memorable moment during her six seasons on The Real Housewives of Beverly Hills. But one of her most classic scenes centers on a plush blue bunny. 

In case you need a refresher, during the Season 7 reunion, Kim Richards gave Lisa back the baby gift that Lisa had sent to Kim's grandson (that'd be the bunny). "It didn't feel like it had good energy; I'm sorry," Kim said back then. At the time, Lisa cried at the slight. But these days, she's all smiles around anything with a cottontail. 

At the October 12 Costume Party Premiere of Kyle Richards' movie Halloween Kills, Lisa donned a big-eared costumed that winked at the classic Season 7 moment. In a giant pink bunny suit, the model mama topped her "iconic hair" with silky bunny ears. She also painted her face with a cute rabbit nose and whiskers. 

At the same event, Kathy Hilton dressed up as a dentist, and Dorit Kemsely dressed up as Kathy's daughter Paris. When it comes to costumes, these 'Wives are truly ... clever rabbits.
