Talk about getting lucky on Saturday night! Or at least on Saturday Night Live. Akon joins Andy Samberg's Lonely Island SNL crew, along with Jessica Alba & Blake Lively, for what is bound to become an anthem of the (barely) sexually active set: "I Just Had Sex." Check it out above. OK, so it's no "D!ck in a Box," or even "I'm on a Boat," but be prepared to experience the best 30 seconds of your life.
