People have been mentioning Bruno Mars for the halftime show for a while, now he’s taken to Instagram to make it official.  It’s a great add considering when he performed in 2014, many people put it up there with the greatest halftime shows ever. The Uptown Funk singer joins an already amazing lineup of Coldplay and Beyonce (not to mention that there are rumors or even more surprises!). Of course the game will get a great musical start too with Lady Gaga is set to sing the national anthem.
