Last night, at a record release party for the band Freesol at his restaurant in NYC, Justin Timberlake grabbed a mike and … sang something. In the video, you can see him singing “Say yeah … Say yeah yeah … Say yeah yeah yeah … Say oh hell yeah … Say you don’t give a fuck … ” but he also did a longer set, including a version of “What Goes Around Comes Around,” guitar playing, and what People is calling a new song with the chorus “Your body’s like a fast car/I’ve got the keys.” A new song?! Miracle of miracles. Timberlake, who will be performing tomorrow at Irving Plaza for Freesol, has been on an indefinite hiatus from music while he focuses on being a serious actor, basically only sings now when he’s promoting his acting career, making a joke, or reminding all the people who prefer him in his musical incarnation that, in the words of Drake, “he’s doing me” now. The clip from last night — which we’re linking to until the video becomes embeddable — does demonstrate that Timberlake still has swaggerific mike-holding technique though.
