Justin Timberlake was back on stage last night at NYC's Irving Plaza, performing a special show with the band FreeSol to celebrate his 901 Silver Tequila line's National 901 Day! In honor of the date 9/1, JT teamed up with FreeSol, who are signed to his Tennman records, to perform some of his old hits — he went from "Cry Me a River" on to "What Goes Around . . . Comes Around," "Like I Love You," and a cover of the Rolling Stones's "Miss You"! JT and FreeSol wrapped things up by even doing some rapping together. It was Justin's second stint behind the mic this week, since JT also performed inside restaurant Southern Hospitality on Wednesday.
