Leading revelers into 2011, Kim Kardashian hosted a New Year's Eve bash at TAO Nightclub at the Venetian in Las Vegas, Nevada on Friday night (December 31).

Looking fabulous in a white frock, the E! hottie was joined by brother Robert and Harold "Hype" Williams while tweeting to her millions of fans, "Who's excited for the new year? Let's leave the past behind us and move forward! Do better and push yourself in 2011!"

And while Kim was busy partying it up in Sin City, sister Kourtney happened to be hosting a fete in the sunshine state at The Rooftop at The Gansevoort Hotel in Miami.

Also looking stunning, Kourtney was the center of attention at the Ciroc New Year's Party with Newyearseve.com, tweeting during the soiree, "Happy New Year! I am having SUCH a great time in beautiful Miami!"
