.@Beyonce celebrated her 38th birthday backstage at the M.I.A. festival.

Okay, so technically her birthday isn’t actually until tomorrow (Wednesday). But that didn’t stop friends and fam from surprising Beyonce with a backstage birthday cake. A fan account on Instagram has video of the group singing “Happy Birthday” to the birthday gal. And of course, hubby Jay-Z was right by her side, holding a bottle of Ace of Spades champagne while gassing the crowd up to sing louder.
