It's a good thing Radio City Music Hall can hold thousands of people, given the ever-expanding lineup of performers and presenters at Aug. 28's MTV Video Music Awards. The latest additions to the performing roster are Beyoncé and Metallica, joining a bill that already includes 50 Cent, Coldplay, Christina Aguilera, and Good Charlotte. In fact, Beyoncé may make several trips to the stage, since she's up for five Moonmen trophies, including four nominations for her ''Crazy in Love'' clip; Metallica have one nomination, for Best Rock Video (''St. Anger'').
Newly named award presenters include Jay-Z, Britney Spears, Sean Paul, Mya, Missy Elliott, tennis champ Serena Williams, Method Man, and the abdominally ripped proto-punk Iggy Pop. Also new to the list are the ubiquitous Fab Five style gurus from Bravo's ''Queer Eye for the Straight Guy,'' as well as unspecified cast members of Comedy Central's ''Crank Yankers.'' They'll be fighting for camera time with presenters P. Diddy, Ashanti, Kelly Clarkson, skateboarder Tony Hawk, Hilary Duff, Ludacris, ''Jackass'' vet Bam Margera, Redman, Evanescence, David Spade, Snoop Dogg, basketball star LeBron James, and the Olsen Twins. Cracking jokes in an opening monologue -- and then, presumably, getting the hell out of the way -- is host Chris Rock.
