In case you were temporarily blinded and deafened at the beginning of 2013 and are only just now regaining your sight and hearing, Justin Timberlake is waging a comeback. And because a new album, documentary, Bud Light Platinum commercial, Grammys performance, and film roles may not be quite enough to keep him on the radar, he’s also joined Instagram. Way to stay current, JT!
Justin’s not the only pop star to join the photo-sharing service, however. Madonna also climbed aboard for some Insta-action.
See their photos after the jump!
