Justin Timberlake 'Courts' Alyssa Milano, Eva Longoria

Justin Timberlake proved he's got game early Saturday morning when he shot some after-hours hoops with Alyssa Milano and Eva Longoria. After his Friday night concert at the MGM Grand in Las Vegas, Timberlake, 25, hit the Jet nightclub with his entourage, where he danced with Milano, 34, and chatted with Longoria, 31.

At 4:00 a.m. the whole crew headed to an after-after party at the Palms' Hardwood Suite in the hotel's new 347-room Fantasy Tower. The $25,000-a-night, 10,000-square suite features an indoor basketball court, complete with scoreboard and locker room.

(The previous weekend, Timberlake's ex, Britney Spears, stayed at the Fantasy Tower's $40,000-a-night, two-story Hugh Hefner Sky Villa with new beau Isaac Cohen.) "Justin played basketball for quite a while with Eva and Alyssa," says a source. He and about 100 other revelers "stayed there for a couple hours."

Timberlake, who announced his split with Cameron Diaz earlier this month, dated Milano after his 2002 split with Spears: They were spotted clubbing in L.A. and playing golf together, though a friend of his told PEOPLE at the time, "Right now they are not boyfriend and girlfriend. They are just having a good time."
