The stars will be ringing in 2011 in style. While a smattering of A-listers, including Rihanna, Jay-Z, and Diddy, welcome the new year in Sin City, other celebs will be spread across the country. Here’s a roundup of what some of your faves will be doing when the clock srikes midnight.

2010’s breakout star Drake will perform poolside at WET at the W Hotel South Beach before the party moves inside to WALL, while his Young Money sister Nicki Minaj counts down the new year in the MIA at Mansion. The Pink Friday rapper can also be seen performing on “NBC’s New Year’s Eve with Carson Daly” at 10 p.m. Her “Bottoms Up” collaborator Trey Songz will toast to 2011 at LUXE across town and Lil Jon will turn up the volume at Cameo nightclub.

Flo Rida will watch the ball drop in New York City’s Times Square with the cast of the “Jersey Shore” for MTV’s “New Year’s Bash 2011,” while down the block Bruno Mars caps a successful year at the R Lounge in the Renaissance New York Times Square Hotel. Fans shelled out $950 for two tickets to catch the Grammy-nominated star and hip-hop icon Rev Run.

Lil Wayne will blow into the Windy City to host his first party since prison at Adrianna’s Club Ballroom. Lil Tunechi and the Dipset gang will pop bottles (or water for Weezy), while fans at home can catch him perform his Carter IV single “6 Foot 7 Foot” on “NBC’s New Year’s Eve with Carson Daly.”

On the West Coast, Rihanna will party like a rock star on the Las Vegas Strip at PURE at Caesars Palace. Also in Sin City, Nelly will shake things up at Haze at Aria, Jay Sean parties like it’s 2012 at The Bank at Bellagio, and B.o.B rocks JET Nightclub at The Mirage. Off the Strip, Ludacris will be pouring bottles of Conjure at Vanity Nightclub at the Hard Rock Hotel.

The man of all celebrations, Diddy, will hold court at LAX Nightclub inside the Luxor in Vegas, but the hottest ticket will be Jay-Z, who performs with Coldplay at the grand opening gala of The Cosmopolitan for a few thousand invited guests. Those lucky enough to be in attendance may catch a glimpse of his wife Beyoncé.
