All the star power in the world couldn’t keep the Lakers from blowing a 24-point lead in their devastating loss to the Boston Celtics Thursday night at L.A.’s Staples Center.

“Good for Boston,” Will Smith graciously conceded to PEOPLE after the Celtics’ 97-91 win. He was followed to the exits by a grim-faced Jack Nicholson, a dejected Penny Marshall and disconsolate Justin Timberlake.

But the crowd - which included L.A. supporters Denzel Washington, Tobey McGuire, David Beckham, Nicky Hilton, Ryan Seacrest, Randy Jackson, Dustin Hoffman and Fergie - did contain a few Boston fans.

“It’s a good year for comebacks,” he told PEOPLE. “For the Celtics and the New Kids on the Block.”

Michelle Kwan was there to cheer on the Lakers - and to admire the players’ fit physiques. “They’re all good-looking,” said the L.A. native. “They have nice bodies …. And then you see that passion for the game.”

But her beloved Lakers are in a tight spot now, down 3-1 in the NBA championship series. (The Celtics need just one more win to clinch the title.)

“I think we’ll win it all in game six in Boston next week, and then we’ll celebrate the night,” Wahlberg predicted.

But would his brother Mark (who’s been - gasp! - rooting for the Lakers lately) join in the fun? “Right now, I think his blood is turning purple and gold a little but,” Donnie admitted, referring to the Lakers team colors. “We’re gonna have to fix that!”
