NEW YORK - Lady Gaga will rock New York's Times Square on New Year's Eve.

ABC said Thursday that the singer is the featured guest on Dick Clark's annual "New Year's Rockin' Eve" special. Clark will appear along with Ryan Seacrest to celebrate the 40th anniversary of his New Year's show, the annual program already teen-aged before Lady Gaga was even born.

Fergie will host the Los Angeles portion of the show. No other musical guests were announced.

It figures to be a long party. Clark's show takes up three hours of prime-time, breaks for local news, then comes back for more than two and a half hours.
