Katie Couric took a jab at former NBC colleague Brian Williams at yesterday’s Matrix Awards, hosted by NY Women in Communications. While introducing honoree Anne Keating, head of p.r. for Bloomingdale’s,Couric described the crowd as a bunch of media queens. Then, looking at Williams, she added, “No, Brian I’m not talking about you.” Williams, who emceed, sat with NBC honcho Jeff Zucker and “Saturday Night Live” star Seth Meyers, who said the mostly female crowd reminded him of “the time I got lost in the women’s department at Bloomingdale’s as a kid.”
