Grab a bottle of champagne and start the countdown to 2009.
Hollywood stars including Lindsay Lohan, Usher, Eva Longoria Parker and Heidi and Spencer will be ringing in the New Year by celebrating – and fulfilling hosting duties – at various hot spots from coast to coast.
In N.Y.C., Mario Lopez will be at Marquee, just a few blocks away from Times Square, where the Jonas Brothers and Taylor Swift will appear live for Dick Clark's New Year's Rockin' Eve special hosted by Ryan Seacrest.
Katy Perry will perform at Gridlock's New Year's Eve party in L.A. while Longoria Parker will host an invite-only soirée (which includes a balloon drop) at her Hollywood restaurant Beso.
Looking to welcome the New Year in some warmer temperatures? Join Lohan and Samantha Ronson at a jungle-themed bash at Mansion or Chace Crawford and Diddy at the Fontainebleau Hotel's 30,000-sq. ft. LIV nightclub in Miami.
For more than 10 parties in a 4-mile radius, head to Las Vegas, where everyone from Heidi Montag and Spencer Pratt to Fergie and the New Kids on the Block will have their own celebrations. Other famous hosts expected in Sin City include Ashlee Simpson-Wentz, Pete Wentz, Usher, Carmen Electra, Benji Madden and the Kardashian sisters.
