The stars, including Hollywood actor Tom Cruise, came out to watch the second game of the NBA's play-off conference finals between the LA Lakers and the Denver Nuggets in Los Angeles.
Madonna's ex Guy Ritchie took time out from making his new film, Sherlock Holmes, to watch the Denver Nuggets square the series 1-1 with a 106-103 victory. LA Lakers won the first game 105-103.
Oscar-winning actor Denzel Washington looked worried as his team lost the game in the final quarter. He's getting ready for the release of his new Tony Scott movie, The Taking of Pelham 1 2 3.
Leonardo DiCaprio looked excited courtside while relaxing after finishing filming off his new movie, Shutter Island, due for release later this year. It's being directed by Martin Scorsese.
Desperate Housewives star Teri Hatcher also looked animated despite the LA Lakers eventually losing. In the other NBA conference play-off final game, Orlando Magic are 1-0 up against Cleveland Cavaliers.
