Where Will The Stars Be Celebrating New Year's?

From down under to down south, celebs will be ringing in 2009 from all over the world!

We already told you about Brit attending her brother's New Year's Eve wedding in Louisiana, and you probably already know about Paris hosting that New Year's bash in Australia, but did you know that John Mayer will be joining Jennifer Aniston and her Friends Courtney Cox and David Arquette in Mexico?

People reports that John and his brothers arrived at a resort in Los Cabos on Saturday, and even though the musician and the "Marley & Me" star will be staying in separate residences, it looks like they'll be just a short walk away from one another! Think we'll be seeing more poolside action?

A source tells X17online that Justin Timberlake and Jessica Biel are currently in Vail, and they'll be ringing in the new year with plenty of snow and snuggle time. Jennifer Lopez and Marc Anthony will be heating things up in Puerto Rico, and Beyonce, Mariah Carey, Donatella Versace, Russell Simmons, Richard Gere, Daniel Craig, Marc Jacobs and a few other celebs will be keeping warm in St. Barth.

Lindsay Lohan and Samantha Ronson will be at Mansion in Miami, and Puff Daddy Diddy, Molly Sims, and Maroon 5's Adam Levine will also be in town to host separate parties at the swanky Fontainebleau resort.

Ashlee Simpson and hubby Pete Wentz will be raising their classes at midnight at Pure nightclub in Las Vegas, the Kardashian girls will host a bash nearby at LAX, and newlyweds Heidi and Spencer Pratt will be getting their party on at the Christian Audigier nightclub.

Taylor Swift and the Jonas Brothers will be causing quite a frenzy in Times Square, as they will be celebrating at The Big Apple's annual ball drop, and according to Access Hollywood, the New York Police Department is expecting a possible “mob scene” tonight when the Jonas Brothers take the stage to perform on Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest.
