It's Showtime!

With the Lakers facing the Celtics in the NBA Finals for the first time in over two decades, a ton of their most famous fans were at the Staples Center to cheer on the home team!

For instance, we caught Jon Voight and his son James Hayden - perhaps better known as Angelina Jolie's father and brother (and former makeout partner), respectively - walking through the parking structure. Which is sweeter, James - the Lakers winning, or making out with your sister?

And, of course, after the Lakers sealed their first win of the series, everyone headed out to celebrate - especially Kendra Wilkinson! The Girl Next Door and her crew did a victory lap on their way into STK to celebrate her birthday, taking their time to show off all their Laker gear before walking in. Unfortunately for Kendra, she took off mere minutes before Lakers forward/center Pau Gasol showed up - aww, so close!

And don't forget about Britney and Mel - they might not have made it out to the Staples Center, but they found their own way to celebrate the big win!
