Julia Louis-Dreyfus had a great reason to celebrate Thursday night as she was spotted in the stands, celebrating Northwestern University's first-ever March Madness win.
The Seinfeld star's unbridled enthusiasm was two-fold: Her son, Charlie Hall, plays for the Wildcats, who were making their NCAA tournament debut. She is also an alumna to the school.
Louis-Dreyfus was seen mouthing the words "oh my God" as the Wildcats stunned with a last-minute, bracket-busting victory over Vanderbilt.
She and her husband, Brad Hall, were decked out in purple and white to represent the school’s colors while cheering for their son and his team.
The Veep actress also tweeted a video of her son doing a locker room interview for CBS Sports. She wrote: “Our boy is caught up in #MarchMadness.”
She wasn't the only notable name catching the March Madness spirit.
New Jersey Governor Chris Christie was surprisingly rooting for Notre Dame, which booted his state's own Princeton from the tournament.
Bill Murray cheered on Xavier as they beat Maryland. The Ghostbusters actor's son is an assistant coach for the team.
