Club Tigerheat lives up to its name every week in more ways than one, packing in young pop-music lovers (mostly gay, some straight) for a feral evening of hookup hunting and floor humping amidst sweat, flashy lights and glossy videos. For next week's celebration of its most beloved pop princess, it's trying out new quarters: the Palladium. Marking the club's single-release party for Britney Spears' “Hold It Against Me,” Tigerheat digs its paws into the famed music venue for one night only, as always, open to crowds 18 and over. Expect all the usual Tigerheat amusements: scantily clad go-go dancers, a VIP area, giant video screens and a midnight performance from dance troupe Barbie's Addiction. Club Tigerheat, 6215 Sunset Blvd., Hlywd.; Thurs., Feb. 10, 9:30 p.m.-3 a.m.; clubtigerheat.com.
