Update: Justin Timberlake is not facing charges for his voting booth selfie taken in Tennessee. Although the Shelby County DA office originally told Entertainment Weekly that JT could get into trouble, the District Attorney General herself, Amy Weirich, has now nixed that. Weirich wrote on her official Twitter account:

Original story (10/25): Justin Timberlake was so psyched to vote that he crossed the country to do it in his home state of Tennessee. He shared his enthusiasm with 37.1 million followers on Instagram, but he did it illegally. Yup: No cell phone use in the voting booth. And a Tennessee law passed in 2015 makes it prosecutable.

“The Shelby County DA’s office was made aware of a possible violation of state election law," the office told Entertainment Weekly in a statement. "The matter is under review of the DA’s office."

The offense is punishable by up to 30 days in jail or and/or a fine that maxes out at $50. Timberlake's post has gotten 470,000 likes as of this publication; he also sent the 'gram to Twitter, where he's got 56.9 million tweeps.
