On his 48th birthday earlier this month, R. Kelly dropped "Happy Birthday," an ode to...his birthday, and everyone else's's birthdays, and birthday parties, and cakes and drinking and...you get the gist. Today, he's back with the accompanying video that is pretty much what you'd expect for what he's calling "The Official Birthday Anthem of 2015.From the strip club to the hotel room and the Sprinter to a boutique, the "Happy Birthday" video is as turned up as one's birthday could ever be. The day after, you'll have to spend some time watching the entire Trapped in the Closet series to nurse the hangover.
