Rather appropriately, Katy Perry's joined up with RiFF RAFF to remix her true-to-style party anthem, "This Is How We Do." Katy's original track shouts out to kids who like to party all week long and don't think twice about it. Based on her lyrics these kids may not be making the best decisions, choosing to spend their rent money on bottle service and staying up until breakfast time, but for party animals like Katy and her crew, this is the dream life: "chillin, laid back, straight stuntin'." RiFF RAFF seems to approve of the same lifestyle, bragging about landing his chopper on top of Red Lobster and filling his sink with champagne, because these are normal activities for ballers on his level. Let's be real, if we all had money to fill our sinks with champagne and valet our private helicopters, we totally would.
