The engine of Future's music has been heartbreak. Since last fall's Monster, the Atlanta rapper has become perhaps rap's biggest star, all off the back of singles, EPs and a number one album that all hinge on the desperate, lonely, drug-addled period of wandering that's followed his split from Ciara. He's bolstered that heavy release schedule with a never-ending series of videos. So far, he's dropped visuals for “Stick Talk,” “The Percocet & Stripper Joint,” “Blood on the Money,” “Kno the Meaning,” “Where Ya At,” “Blow a Bag,” “Real Sisters” and “Fuck Up Some Commas,” as well as a rumored clip for "Thought It Was a Drought." But today (Nov. 19) we get "Rich Sex," which stars Future and Blac Chyna in sultry roles. Rumors about a possible relationship between the two have swirled since Chyna got the word "Future" tattooed on her hand; Future denied any romance. The kicker? It's Tyga's birthday.
