Pictures of Matt Damon, Zac Efron, Brooklyn Decker at Celtics vs. Lakers Game in LA 2011-01-31 07:36:32

Matt Damon was a very passionate Boston fan at last night's Celtics vs. Lakers game at the Staples Center in LA. The East Coasters managed to win 109-96, much to the dismay of most of the stars in attendance. Zac Efron and Leonardo DiCaprio are loyal supporters of the home team and braved the rain to enjoy the Sunday afternoon matchup. Brooklyn Decker tweeted that her front row seat next to Adam Sandler was "work" as the twosome get to promoting Just Go With It. Their costar Jennifer Aniston didn't join them, though she did have her own fun weekend out in the city. All the stars watching the Celtics-Lakers meant they didn't join in the SAG festivities, where the rest of Matt's True Grit cast celebrated despite not taking home any statues. Leonardo has so far skipped award season, but he attended Saturday's DGA event and may show up to next month's Oscars, where Inception is up for best picture.
