Comedian Kathy Griffin is no stranger to controversy – or CNN (and sometimes together). She has hosted the New Year's Eve special with Anderson Cooper for the past few years, and she's been a guest (and host) of "Larry King Live."
Tonight she goes head-to-head with Piers Morgan for the first time. Live for the hour. Sarah Palin? Casey Anthony? Nothing is off limits. Tune in 9pmET – our control room is dusting off the bleep button...
(Above: check out Griffin and Cooper as the welcomed 2011.)
> Update: We'll also have the latest on the market collapse, with Erin Burnett, Ali Velshi and Kai Ryssdal.
