She hit the downtown Manhattan celebration with her 19-year-old son, August, and their outfit coordination was absolutely top-tier. August rocked an epic orange and blue “Marknicksa Hargitay” shirt, while the 62-year-old actress wore a custom top reading “Brilliant Thing #11 The Knicks”—a clever nod to both her Broadway show and Knicks MVP (and her BFF!) Jalen Brunson.

The diehard fan didn’t just watch from the sidelines, either; she actually ended up celebrating right on Brunson’s float alongside his family! This iconic parade appearance comes right after Hargitay and her “SVU” co-star Christopher Meloni had a viral Jumbotron moment sitting courtside at Game 3 of the NBA Finals.
