Justin Timberlake was back in formal attire for his latest afternoon on set in LA yesterday. He got to work filming the video for "Suit & Tie" with Jay-Z last week, just before hitting the red carpet for the SAG Awards. Since he released the new track earlier this month, Justin's schedule has kept filling up, with the latest announcement revealing he'll perform at the Grammys and the Oscars. There are plenty of reasons to get excited about seeing Justin on stage at the Grammys, but we might not have to wait that long to hear him live. Rumor has it that Justin may join Beyoncé Knowles during the Super Bowl halftime show in New Orleans on Sunday.
