Yesterday we announced that Saturday Night Live will be adding a new female cast member named Kate McKinnon. We didn't know much about her at the time, other than that she frequently performed at the UCB theater, but we now know a little more about her. She actually has a sketch comedy background, starring on the Rosie O'Donnell-produced The Big Gay Sketch Show for all 3 seasons on the LOGO network. (She will also be SNL's first ever out lesbian cast member.) Here is a clip of her signature character Fitzwilliam, a British boy whose only wish is for a vagina. Just hit the big PLAY button below to watch.
