Jamie Foxx still knows how to party.

The actor started Tuesday evening uptown, giving a 45-minute performance and bantering with a crowd including Michael Milken, David Geffen, David Foster and Katharine McPhee at a benefit for the Prostate Cancer Foundation. “Everyone got on their chairs,” an attendee said of Foxx’s audience.

After the event, which raised $5 million, Foxx headed to Brooklyn Chop House with an entourage of 30 friends. We’re told when the music was turned up, “he jumped up and began salsa dancing with a patron and the waitstaff.” He stayed till 5 a.m. and left a $2,000 tip.

Meanwhile, Realtor.com reports Foxx’s ex Katie Holmes is selling her Calabasas, Calif., home for $4.6 million.
