Holy Schmidt, Max Greenfield’s TV mom is a Sweeney sister!

New Girl has tapped Saturday Night Live vet Nora Dunn to guest-star as Schmidt’s never-before-seen mother, TVLine has learned exclusively.

Dunn’s straight-outta-Long-Island, controlling matriarch, Louise, is always ready with unsolicited advice or a piece of chocolate.

In November, Dunn appeared on another Fox sitcom, Mulaney, as the title character’s mom.

Look for mother and son to be reunited in a March episode.
