Kathy Griffin & Anderson Cooper, New Years 2009

Griffin and Cooper, New Years 2011

Anderson Cooper and Kathy Griffin will again co-host CNN’s New Year’s Eve celebration from 11pmET to 12:30amET. “Get ready, America. Pull up a chair and a box of your finest wine, because you’ve never seen a New Year’s Eve show like this,” said Griffin. “Kathy Griffin scares me. I’ve said this often to CNN management directly and through my attorneys,” joked Cooper.

Last year was pretty tame compared to the year before when Griffin dropped the “F” bomb and the year before that when she heckled an onlooker. Top those, Griffin.

Isha Sesay will join Cooper and Griffin from the crowds in Times Square and Gary Tuchman will report live from Central Park for the annual Midnight Run. Correspondent John Zarrella will be live in Key West, Florida and Brooke Baldwin from Nashville, Tennessee. The show will simulcast on CNN International.

Leading up to the 11pm special, CNN presents the “Best and Worst of 2011,” an Anderson Cooper 360° special anchored by Tom Foreman.
