They’re still talking about Justin Timberlake’s surprise performance with Free Sol at Southern Hospitality, the Manhattan barbecue restaurant he helped launch the other night.  He performed to a packed house after Tweeting an invitation earlier in the day.

According to,  newlyweds Kim Kardashian and Kris Humphries were on hand for the performance along with Kim’s sister Kourtney.  Also spotted was Timberlake’s "In Time" costar Amanda Seyfried.

Seems like Timberlake was promoting the band Free Sol, which is signed to his Tennman Records.  Both perform at the restaurant with Timberlake performing a an cappella version of his hit “What Goes Around...Comes Around.”
