Smith took to his newly created account on Friday to thank Timberlake for the post, before offering him some hilarious advice for his upcoming Super Bowl halftime performance.
"JT! Thanks a lot man for the post, the brief education about Instagram, man, because this is my first day, so I appreciate the hookup. But I know what Throwback Thursday is, man. I ain't been in a hole," Smith said, before sharing "things to avoid at the Super Bowl" -- and flashing his nipple!
"Avoid that. Avoid that," he said with a laugh, obviously referencing Timberlake's last time on the Super Bowl halftime stage in 2004, when he exposed Janet Jackson's breast.
"I'm stupid," Smith cackled. "You're the man, I love you."
