The actress and the Strokes drummer were spotted together taking in a game on Sunday, sitting courtside as the New York Knicks lost to the Minnesota Timberwolves.
Wiig, 40, and Moretti, 33, have been tight-lipped since they started dating almost two years ago, and made no comment when they allegedly said their goodbyes this summer. Sources said the breakup was "amicable" and they would remain friends, and they were spotted grabbing coffee in Brooklyn two months later.
Back in August 2012, Wiig did open up, vaguely, about their relationship.
"I will say that I'm happier than I've ever been, and I feel very lucky right now," she told Marie Claire. "Where I am now. Who he is. Those are the big ones."
