On Wednesday evening in NYC at his Southern Hospitality restaurant, Justin Timberlake surprised diners with an off the cuff concert.

A few short hours before taking to the stage, the “Friends with Benefits” actor took to his Twitter to inform fans that he would be performing. No doubt people rushed down to the eatery to catch the show. A few celebs were even spotted in the crowd, including famous newlyweds Kris Humphries and Kim Kardashian, along with actress Emma Roberts.

After winding down when singing “What Goes Around” he said to the crowd with a smile, “Thanks for your help. It’s been a long time.”

The very next night, JT sang back-up for progressive Hip-Hop/Rock/Soul band Free Sol at their 901 Silver Tequila concert at Irving Plaza, and he must have caught the performance bug once again, because he performed an array of his own hits such as “Like I Love You,” “Dead & Gone,” and “Cry Me a River.”

“I’m too old for this sh-t!” he joked when performing. “For the record, I’m not trying to become a serious actor you f—ers!” he blurted out, hinting at a possible return to music.
