Rick Ross was the headliner Friday night at the Magnises party at Villain in Williamsburg, but the larger-than-life rapper performed for a mere 20 minutes before peacing out.

But the crowd that stuck around — largely comprised of male models — was rewarded later in the night when Ja Rule showed up as a surprise guest.

The rapper, who just announced a new reality show on MTV, hung out onstage with friends, drinking as the audience stood wondering what was going on. Eventually, he grabbed a mike to spit a few hits, including “New York.”
