NBA Playoffs Madness: Basketball's Biggest Celebrity Fans

A diehard Boston Celtics fan and a Boston, Massachusetts native, Matt Damon isn't afraid to don his Celtics gear even in a stadium full of Laker fans.

The huge Lakers fan was for once on the receiving end of the joke when Kobe Bryant studiously ignored his attempts to make conversation with him during last year's Game 1 of the NBA Finals against the Boston Celtics.

Frequently spotted with best bud and fellow Laker fan Leonardo DiCaprio at the Staples Center, Tobey now attends most home games with his wife Jennifer Meyer.

Matthew Perry will always be the Lakers' favorite "friend".

The rapper/actor showed his Lakers support by recording the  "2010 L.A. Lakers Anthem" with Ray J, Chino XL, Roscoe Umali, Lil Rob and the New Boyz last year.

Ashton Kutcher and wife Demi Moore often make their date night "Laker night".

Red Hot Chili Peppers frontman Anthony Kiedis sings a song called "Magic Johnson"off their 1989 album Mother's Milk, named after the Lakers legend himself. How's that for dedication?

A Miami Heat fan, game cams often catch him laying low with longtime squeeze Anna Kournikova.

He owns part of the New Jersey Nets.  Need we say more?

A diehard Knicks fan and a proud New Yorker in general, Spike Lee is known to come to Madison Square Garden games dressed head-to-toe in his favorite team's gear.

At first solely at the Laker games with ex-boyfriend Zac Efron, Vanessa has since turned up at games with either her little sister Stella in tow, or rumored new squeeze Josh Hutcherson.

Zac is frequently seen chatting with fellow big ticket holders Leonardo DiCaprio and David Beckham courtside at his countless Staples Center appearances.

Turns out the superstar has a deep appreciation for a sport other than soccer.

The low-key Laker fan is an avid basketball follower, even playing a young drug addict who plays hoops in 1995's 'The Basketball Diaries'.

Perhaps the most diehard celebrity sports fan there is, there's no denying Jack's dedication to his beloved Lakers.

There is perhaps no better place to go star sighting than a Los Angeles Lakers game.  But to ease the pain of the Lakers' sweep by the Dallas Mavericks this year, and in honor of the NBA Playoffs madness which is only set to heat up from here, check out some of b-ball's biggest celebrity fans.  Because when it comes to balling, there's no stopping some of the sport's biggest and busiest fans from taking in a game just like the rest of us...only their seats are courtside.
