Justin Timberlake's recent attempt to encourage U.S. citizens to vote in the upcoming presidential election may actually land him in jail. Oops!

The “Can’t Stop The Feeling” singer posted a photo to Instagram yesterday (October 24) of himself voting early at a polling location in Memphis. He implored his followers to do the same, noting he took a plane from Los Angeles to Tennessee to cast his ballot.

"Hey! You! Yeah, YOU!” Timberlake wrote. "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! If you don't, then we can't HEAR YOU! Get out and VOTE! #excerciseyourrighttovote."

It was, at first, a welcome gesture of encouragement, but it turns out it’s also illegal to take photos or record audio while in the voting booth, according to TMZ.

Timberlake could possibly face a 30-day jail sentence and be forced to pay a $50 fine, as per a Tennessee law that passed last year.

But while Timberlake's case is currently “under review,” according to a representative from the Shelby County District Attorney’s Office, a member of the election’s board where he voted says the Trolls actor should not be punished for urging others to vote and should be commended instead.
