With Eminem, Britney Spears, Bruce Springsteen and P. Diddy set to boogie before a packed crowd at the annual MTV Video Music Awards on Thursday, ever-edgy cops won't be taking any chances about security.

When Jimmy Fallon, of Saturday Night Live fame, takes the stage at Radio City Music Hall as emcee, agents from the bomb squad will already have scoured every inch of the theater, officials said. The 18th annual show is being held a week earlier than usual, so it won't interfere with 9/11 anniversary ceremonies. 

A joint terrorism task force will be posted throughout Rockefeller Center during the show, and Emergency Service cops will be stationed inside and out. 

"There is no information of any threat for the MTV Music Awards. It's just part of our stepped-up vigilance since Sept. 11," said a police source. 

"But it's a high-profile event that will be shown live on TV, and we have to make sure that nobody tries anything in order to make a statement."
