The socialite - who reached the milestone age on 17.02.11 - held a `Moulin Rouge`-themed party at V-Moda Fortress, a private house in the Hollywood Hills, on Wednesday night (16.02.11) and the bash had its own petting zoo. The miniature menagerie featured a lynx, porcupine, squirrel monkey and sloth for guests to meet and was the blonde beauty`s first stop when she arrived at 11pm. A source told E!: "Paris loved the animals and made sure that the handlers were humane before she worked with them. She asked a lot of questions about their care." Paris was joined for the special night by her boyfriend Cy Waits, sister Nicky and parents Rick and Kathy, and a host of other guests including Kathy Griffin. Refreshments on hand included absinthe, champagne and cocktails, and revellers also snacked on mini-burgers, mini-grilled cheese sandwiches and other canapes. There were also two cakes for the birthday girl. One of the baked treats was decorated with a photograph of Paris, while the other had black and red icing and was multi-tiered. The evening was recorded for the blonde socialite`s new reality TV show `The World According To Paris`.
