NEW YORK — The New York premiere of "Notorious" may have brought out stars like Jay-Z, Diddy and Spike Lee. But the afterparty at Roseland Ballroom is where the real action was on Wednesday night. Hundreds of people packed the venue and danced to the tunes DJs Cassidy and D-Nice were spinning.

Cast members Angela Bassett, Jamal "Gravy" Woolard and Anthony Mackie, as well as many people depicted in the film were all in the house — even Diddy made a quick appearance. And Brooklyn was more than accounted for, as Junior M.A.F.I.A.'s Damion "D-Roc" Butler, Money L and Lil' Cease made their way in.

The setting for the party was ripped straight from the pages of Biggie's life.

There was an ice block in the of the place carved into the word "Notorious," just like there was at one of Big's album-release parties back in the day. Partygoers were rocking Coogi sweaters. A few Versace shades were spotted in the crowd. And the scent of some illegal substances may have been evident.

"Y'all here to party for Biggie?" Big's wife, Faith Evans, asked the crowd unexpectedly, asking the DJ to cut the music so she could speak.

"Say 'Yeah!" she continued. "I see D-Dot in here. Shout-outs to the Bad Boy family. But where's Brooklyn at?"

The atmosphere was festive throughout the night. Big's former stylist, Groovey Lew, told a story about a Biggie artifact he still has.

"I got this old, yellow sheet of paper," he told MTV News. "Big wanted to remember something, and he asked me if he could borrow a piece of paper to write it down. He didn't want to forget. So he wrote down, 'Money, hoes, and clothes all a brother knows.' "

Those lyrics, of course, would later become a part of the Brooklyn Don's hit "Big Poppa."

DJ Premier, the Beatnuts' Psycho Les and Mase's Harlem World alum Cardan were among the others in attendance.

The after afterparty — which kicked off at 3 a.m. — was held at NYC hot spot Mr. West. D-Nice manned the tables again, spinning some old-school Prince and a couple Biggie cuts too. "Soul Food" actress Malinda Williams was there, as was former Vibe editor in chief Mimi Valdes, who penned the mag's first cover story on Biggie. She teared up after the movie, remembering scenes from the flick ripped from her story.

"It's like 1995 all over again tonight," she said.
