We here at GDD™ just love butts. We also love AC Slater. We also love Riton. Lucky for us, we get all three today as AC Slater & Riton came together to make a sweet little booty of Rihanna’s Only Girl In the World, and our bud AC is giving it away for free today on his Facebook. Grab the track below and make sure to head over to AC’s Facebook and like him!
