Justin Bieber has just completed vocals on his latest project: A guest spot on The Simpsons. The 18-year-old singer, who wasn’t born when the animated Fox comedy launched, tweeted this afternoon: “just did a voice over for the SIMPSONS!!! #swaggy.” Though the tweet appears to have since been deleted, Simpsons exec producer Al Jean confirms to EW that Bieber will indeed play himself in an upcoming episode. How exactly does he fit into the story? “He tries to get into a talent show that Bart is playing piano in and they won’t admit him,” says Jean, quipping: “Draw your own conclusions.”
