Hilary Duff marked the New York Knicks' recent NBA championship win by performing in a specially designed T-shirt during her sold-out concert at Madison Square Garden on Thursday.

The singer wore a New York or Nowhere Knicks 2026 NBA Championship T-Shirt, a piece from the apparel brand's official collaboration with the team. Duff, who also expressed her support by chanting "Knicks in 5, Hilary in 2!," has lived in New York, including Brooklyn while filming the television show "Younger."

Duff's daughters made a surprise appearance on stage during the concert, joining their mother for pizza. The singer noted that her 5-year-old daughter, Mae, has expressed a desire to move to New York City.

The concert featured performances of Duff's popular songs from the 2000s, such as "The Math," "Come Clean," and "What Dreams Are Made Of."
