His tryout is highlighted in a new teaser for the show's final season.
In the clip, shared by his wife Kim Kardashian West on Twitter, the rapper introduces himself to the judges' panel by saying, "My name is Kanye. I'm from the South Side of Chicago. I'm originally a producer."
"I always wanted to rap and no one really believed in me, so I wanted to try some things out, you know?" he continues.
Kardashian West is also featured in the video, telling host Ryan Seacrest, "I'm not nervous because I do really believe in him."
"It's YEEZY season! Can't wait for you guys to see Kanye on @AmericanIdol in January!" she wrote in her tweet.
