The 18-year-old will be seen trying to enter a talent contest in which Bart is also participating, reports ew.com.
Bieber shared the news on Twitter and wrote : “Just did a voice over for the ‘The Simpsons!’ !! Swaggy.”
Executive producer of the show Al Jean also confirmed the news.
“He tries to get into a talent show that Bart is playing piano in and they won’t admit him. Draw your own conclusions… It’s a cameo, but all of his fans should watch every minute of the show, before and after he’s on,” Jean said.
