Justin Timberlake in hot water over US election vote selfie

Justin Timberlake has come under fire for posting a selfie of himself voting in the US election.

The 35-year-old shared the snap of him in a Tennessee polling station with the caption: "Get out and VOTE! #exerciseyourrighttovote."

He told his 37 million Instagram followers he had travelled from LA to his hometown of Memphis to cast an early vote.

"There could be early voting in your town too. If not, November 8! Choose to have a voice!" he added.

But the photo could have got him in hot water as Tennessee law prohibits voters from recording or taking photos or videos inside a polling station.

A person convicted of the violation can be sentenced to 30 days in jail and fined $50.

However, the Shelby County district attorney's office said it was not investigating.

Shelby County District Attorney General Amy Weirich said: "No one in our office is currently investigating this matter nor will we be using ourlimited resources to do so."

A representative for Timberlake did not respond to requests for comment.
