Mike "The Situation" Sorrentino and Good Charlotte kicked off an exciting New Year's weekend bash at Chateau Nightclub & Gardens at Paris Las Vegas last night. Reality star and fashionista, Nicole Richie, NBA legend, Julius "Dr. J" Erving, and gorgeous singer, Brandy, also celebrated the end of the year at the stylish nightclub.

Sorrentino is looking forward to getting some rest in 2012. "My New Year's resolution is to take it easy and relax more," said the Jersey Shore hunk.

But, that resolution would have to wait -- Sorrentino was anything but relaxed as he enjoyed celebrating the end of 2011. The MTV star yelled "Happy New Year" to fans and even threw his jewelry into the crowd.

Good Charlotte performed on the rooftop nightclub of Chateau Gardens. Brothers Joel and Benji Madden, as well as the rest of the band, gave fans an incredible once-in-a-lifetime performance under the Eiffel Tower of Paris Las Vegas as they sang "Lifestyles of the Rich and Famous," "Dance Floor Anthem" and more.

Nicole looked on and cheered for her man throughout the performance.
