The US Open is finally over. Osaka beat Serena, and Djokovic beat del Potro. Though really, no one's a loser here - the 1st place winners take home $3.8 million, 2nd place winners take home $1.85 million, semi-finalists take home $925,000, and so on and ridiculously so forth. 

But we digress. Everyone knows the US Open isn't really about the money. It's about the celebrity speculators. From Meryl Streep's Oscar-worthy performance as "shocked fan," to Jerry Seinfeld's anxious huff and puff, click through for some of the best celeb sightings from the stands!
