Kim Kardashian -- Valley Girl

7/5/2007 12:48 PM PDT
Sex-vid-a-licious Kim Kardashian ditched Paris Hilton's cool Malibu beach party for a more glamorous fireworks display ... at a high school in the glamorously sweltering San Fernando Valley?

Yes, the Queen of all Booty hit up the beach bash with buddy Aubrey O'Day of Danity Kane, but the two bolted from the breezy 'Bu for the blistering heat of a San Fernando Valley hang -- where they'd no doubt be surrounded by post-barbecue families instead of barbecued celebs like Jared Leto and Dave Navarro.

Kim knows what's hot.
