"I just flew from LA to Memphis to #rockthevote !!! No excuses, my good people! There could be early voting in your town too. If not, November 8th! Choose to have a voice!" the singer wrote.
Unfortunately for Timberlake, as of 2015, it's against Tennessee law to take pictures or recordings in the voting booth, according to TMZ. Doing so means a $50 fine and potentially 30 days in jail.
Moreover, the Shelby County D.A.'s Office told TMZ that the selfie is being reviewed.It's unlikely Timberlake will actually go to jail. Since being enacted last year, no one has been prosecuted for voting booth selfies.
