Paris Hilton is planning to celebrate her 27th birthday by performing with burlesque troupe the Pussycat Dolls in Las Vegas. The sexy socialite will host an 80s-theme party at Los Angeles club Area this weekend (09Feb08) before heading off to Sin City in her underwear. She says, "I'm going to perform with the Pussycat Dolls. I'm going to go to Pure and LAX." Hilton turns 27 on 17 February (08) and admits there's only one major thing on her wish list - an English lover. She adds, "There are cute boys in London. I have to go over there and check them out."
