So much for "retiring" from music for a bit! Justin Timberlake, who has admitted that music is purposely on the backburner for him right now, made his second live appearance in New York City in a week on Thursday, Sept. 1. JT commandeered the stage midway through FreeSol's set at Irving Plaza; FreeSol are signed to JT's Tennman record label, so he is really showing his support! Not only does he direct the band's videos, but he also performs with them and helps generate a buzz!

Wearing a hat and strapping on an acoustic guitar, Timberlake played an acoustic version of his smash dance hit 'Cry Me a River,' with plenty of vocal assists from the flip cam holding crowd. It was intimate and authentic. We almost forgot what a musical talent JT is, since we were too busy laughing because of his comedy routines on 'SNL' and his recent batch of films. He certainly turned a polished pop song into an acoustic jam when he stripped 'Cry Me a River' down.

JT also played 'Like I Love You' with help from members of FreeSol, but then he stopped mid-song, claiming he was "too old" to play the song.

Timberlake also played a surprise show with FreeSol on Wednesday at his Southern Hospitality bar in NYC on Wednesday. Looks like JT is creeping back into performance mode. He's bringing sexy and himself back to the stage!
