Justin Timberlake is in hot water over his voting-booth selfie

Pop star Justin Timberlake on Monday urged his more than 37 million Instagram followers to get out and vote during this presidential election cycle — but did he break the law in the process?

Timberlake, who lives in California, posted a photo of himself early voting in his home state of Tennessee, where he also owns property.

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

But among the millions who saw the now-viral photo was Shelby County District Attorney Amy Weirich, whose office is now looking into the potential violation of Tennessee's election laws, the Memphis Commercial Appeal reported Tuesday.

Referring to one of the singer's most popular hits, Weirich's office said in a statement:

We're thrilled Justin can’t stop the feeling when it comes to voting so much that he voted early in person and is promoting voting to his millions of fans. In Tennessee, using electronic devices inside polling locations to take pictures, videos or make calls is not allowed. We hope this encourages more people than ever to vote, but Tennesseans should only use their phones inside polling locations for informational purposes to assist while voting, like our free GoVoteTN mobile app. If polling officials discover someone violating this law they will ask the voter to put their phone away.

The Tennessee state legislature passed a law last year banning the use of electronic devices inside polling places, unless voters are using them to research candidates and issues. Gov. Bill Haslam, a Republican, later signed the measure. The law took effect Jan. 1.

A representative for Timberlake did not immediately respond to a request for comment from TheBlaze.
