Will Smith and Justin Timberlake have been tight for a while, which is not exactly a secret. They're similarly talented with similar senses of humor, so it makes sense. But their presence on social media differs quite a bit. Justin embraced most platforms pretty quickly, but Will? Not so much. He's a newbie to Instagram now, and we can't think of anything more appropriate for his new account than a video picking on Justin.
As soon as we saw the video was directed at Justin, we knew there would be a roast. We weren't expecting Will to take it where he did, though.
Will warned Justin to avoid repeating the infamous 2004 "Nipplegate" incident when he next graces the halftime stage.
