Where Will Kim Kardashian, Lady Gaga Party On New Year's?

From New York to L.A., celebs have plans to ring in 2012 with a bang.

New Year's Eve is the last chance you'll have to party in 2011. And as the days to plan out your big night begin to dwindle, MTV News is rounding up some of the biggest parties on the planet. From Los Angeles to New York, there's something for everyone.

The Kardashians will be hosting several parties all over Las Vegas. Kim will be at Tao (for a fee of reportedly $600,000), Kourtney, along with the Madden Brothers, will party it up at Chateau Nightclub & Gardens at Paris while Rob has it on lock at Tryst.

Other big Sin City parties include Chris Brown's shindig at Pure, Mary J. Blige's bash at RPM Nightclub, Bruno Mars at The Bank and B.o.B at LAX (the club, not the airport). Fergie and will.i.am will both be in Vegas to ring in 2012. The Black Eyed Peas' leading lady will be at 1OAK, while will.i.am be DJing at Surrender. Professional party rockers LMFAO will be shufflin' all night long at Haze Nightclub at Aria. Newly engaged John Legend will perform at the Palms with T-Pain and Paul Oakenfold.

As celeb-filled as it may seem, not all the stars will be in Vegas. In Los Angeles, Mario Lopez is hosting a party at Hollywood & Highland that boasts performances by Lupe Fiasco and Cobra Starship. And in Chicago, "American Idol" alum Lee DeWyze will be at the Hard Rock Hotel with DJ Chris Kennedy (Chris Masterson) spinning tunes. Kanye West's plans have yet to be determined, but he recently tweeted he's looking for a place to DJ right into 2012. We're sure someone will find a place for him at their party.

New York is the home of all things New Year's. Lady Gaga has been booked to perform on two NYE specials: the 40th annual "Dick Clark's New Year's Rockin' Eve" and the Japanese program "Kohaku Uta Gassen."

For those who want to snuggle up on their couch and avoid all the partying madness, MTV has your back. This year Demi Lovato, Mac Miller, Selena Gomez, J. Cole, Jason Derulo and more will be on hand for "NYE in NYC 2012," which will air live at 11 p.m. ET on Saturday (December 31) from Times Square, where the famous ball drops on, you guessed it, MTV.
