Justin Timberlake is under investigation posting a selfie on Instagram from the polling booth. 

A spokesperson for the Shelby County District Attorney's Office told The Independent UK that they are looking into the incident which may have seen Timberlake break a newly enacted law in his home state of Tennessee.

The musician turned actor posted the selfie to his 37 million followers in a bid to encourage them all to vote. The post, which has since been deleted, was captioned:

“Hey! You! Yeah, YOU! 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.”

A bill was signed into law last year, banning photos and videos from the polling booth. Violating election law is a Class C misdemeanor and is punishable by up to 30 days in jail and/or by $50 fine. 

Somehow we doubt Timberlake will see any jail time over this and will feel any forthcoming fine will be worth it.
