Now that Justin Timberlake is a free man and all, he's hitting the town with a vengeance, dropping by his Hell's Kitchen restaurant Southern Hospitality last night for an impromptu free concert. Much screaming ensued.

J. Timbs had cryptically tweeted "NYC!!! Wanna check out some live music tonight?? Meet me and @freesol at 45th & 9th at 11pm," just hours before showing up and busting a move with the band FreeSol, who just so happen to be signed to Timberlake's record label. Hundreds of fans showed up and filled the BBQ joint to capacity, along with newlyweds Kim Kardashian and Kris Humphries, plus Amanda Seyfried and Emma Roberts.

Timberlake played a "rap ballad" called "Don't Give It Away," and an a capella version of "What Goes Around... Comes Around" during the 45-minute set. TMZ has video of the performance, and you have one more chance to see JT in the flesh—tonight at Irving Plaza, again with FreeSol. Start preparing your vocal chords for maximum high-pitched output now.
