Every good party needs a reboot eventually, and Giorgio’s, the three-year-old dance party that takes place at The Standard Hollywood on Saturday nights, is no exception. So nightlife impressario Bryan Rabin and DJ and music producer Adam Bravin on Saturday launched “Giorgio’s Chapter 2 — The New Sound” at the hotel’s discothèque, drawing loyal friends and fans from all walks of Hollywood life, including actors Alexander Skarsgård, Alan Cumming and Lisa Edelstein; burlesque star Dita Von Teese; producer Donald Deline; socials Jessica de Rothschild, Alexandra von Furstenberg, Sally Horchow and Leah Forrester (who has a new Bravo show called “There Goes the Motherhood”); photographers David LaChapelle, Andrew MacPherson, Amy Neusinger and Alix Malka, and designers Paula Thomas, Michael Schmidt, Brian Wolk, Claude Morais and Janie Bryant. Singer Leona Lewis also used the party to celebrate her birthday while “It” band The Struts turned out to hear the music, and so did Jody Watley and Kevin Haskins of Bauhaus.

Also in the mix was club performer James St. James, whose 2007 best-selling novel “Freak Show” was adapted into a screenplay and film produced by Rabin with Drew Barrymore’s Flower Films and Maven Pictures. It’s also Trudie Styler’s directing debut and stars Bette Midler and AnnaSophia Robb. While Midler wasn’t present at the club, costar Ian Nelson was.

The evening’s entertainment highlight was more dancing of the exotic variety, when Miss World Burlesque champion Kitten Deville’s performed a striptease to Joan Jett’s “Bad Reputation,” followed by theremin player Armen Ra’s rendition of the aria from the Catalani opera “La Wally” sung in the Eighties cult movie “Diva.”
