Justin Timberlake has landed himself in hot water.
The star unknowingly broke the law by posting a selfie in a voting booth – and could now face jail.
The singer posted a picture of himself voting at a polling station in his hometown of Memphis, Tennessee.
He captioned the image: “Hey! You! Yeah, YOU! I just flew from LA to Memphis to#rockthevote 40 !!!”
He added: “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”
However state law in Tennessee prohibits voters from taking photos or making recordings in the booths.
Those who break the law can be slapped with 30 days in jail and a $50 fine and the local District Attorney’s office is now investigating.
An official from the Shelby County District Attorney’s office said the singer’s case is now “under review”, TMZ reported.
However a local representative from the city’s election board, told the website the 35-year-old should be commended, not prosecuted for encouraging people to go out and vote.
The “Can’t Stop the Feeling” singer had made the trip from LA to Memphis to vote early in the presidential election.
Although he did not reveal who he had voted for in the post, he and wife, actress Jessica Biel, 34, are both known to be Hillary Clinton supporters.
They even held a Hollywood fundraiser for the Democratic nominee back in August.
