Paris Hilton put away her bikinis and threw on a sweater to celebrate her aunt Kyle Richards's birthday in LA last night. Kyle got started celebrating her big day by getting lunch at Villa Blanca with her Real Housewives of Beverly Hills buddy Lisa Vanderpump — the restaurant, owned by Lisa, made their cast-mate Taylor Armstrong's list of her favorite places in the city! The girls kept the party going with a mariachi-filled dinner at Frida, and Lisa apparently helped herself to a few margaritas and may be feeling the aftereffects today. The guest list at the meal also included Nicky Hilton, her photo-taking boyfriend, David Katzenberg, Paris's man, Cy Waits, and Kyle's hunky husband, Mauricio Umansky. Nicky, though, wasn't thrilled with the live music at the restaurant! Paris sent a special Twitter shoutout to her aunt following a long day at a Vogue shoot with Terry Richardson, writing, "Love you so much! So happy for you and so proud of you!" The relatives share a common link of their success in reality TV, and there's lots more Kyle drama to come on her Bravo series this season considering her ongoing feud with Camille Grammer.
