BUZZ CLUBS

Birthday? Let’s make it a date

Paladar’s got “Happy Birthday” on heavy rotation. Such young glitter guys and dolls as J.C. Chasez and Paris Hilton have celebrated their birthdays at the hip Cuban eatery in recent days. On Feb. 17, Hilton rang in her big day dining on steak and lobster with her parents, boyfriend Nick Carter, Tara Reid and Nicole Richie. And two nights ago, Chasez invited 35 of his closest friends to the Hollywood hotspot for a b-day blowout.... In more birthday news, Green Day’s Billie Joe Armstrong celebrated at Three Clubs in Hollywood Feb. 18. Among the punx in the hizza were his bandmates Tre Cool and Mike Dirnt, rocker Tommy Stinson, magician Rob Zabrecky, Frontier Records owner Lisa Fancher and filmmaker John Roecker, whose latest tour de farce is a stop-motion puppet movie about Charles Manson called “Live Freaky! Die Freaky!”

Metal, by any other name

The song remains the same: The Viper Room’s Monday night rock club, Camaro, is still steaming up the Strip despite a nom de change. The howlingly funny house band, Metalshop, now goes by the name Metal Skool.... Courtney Love rocked the Viper on Friday, as she played tracks from “America’s Sweetheart.” Her new song “Sunset Strip” is the most blazing ode to paradise lost since Guns N’ Roses’ “Welcome to the Jungle.” This week’s Hot Rock award goes to the Chelsea Smiles (formerly the Disciples), who ripped it up at the Thunderbird Saloon in NoHo on Saturday with a smokin’ 25-minute set. You can check ‘em out tonight at the King King in Hollywood.... The cover band du jour is Ants Invasion, a Seattle-based Adam Ant tribute band that rocked Spaceland on Friday in full war paint.... Oscars week has turned into a big coup for Camp Freddy, the rock ‘n’ roll supergroup who headlined Monday’s “A Diamond Is Forever/SoHo House” bash in the Hollywood Hills, as well as “Ten,” a mondo fashion event hosted by General Motors on Tuesday. On Monday, Camp Freddy -- which includes members of Jane’s Addiction, Guns N’ Roses and the Cult -- was joined by guest vocalists Macy Gray, Steven Jenkins and Mark McGrath. They blazed through Thin Lizzy’s “Jailbreak” and the Clash’s “Should I Stay or Should I Go?” Um, stay.... And just when you thought it was safe to skate, the L.A. Derby Dolls hit town on Saturday night, transforming downtown L.A.’s Set Shop into “Club Derby.” Nearly a thousand people came out in the rain to cheer on the all girl “quad squad,” i.e., four wheelin’ vixens, as well as the featured go-go dancers and mud wrestlers. Sounds dirty.
