Big Sean is set to have a stellar year. The I Decided rapper is going on tour this spring, but before that, he's set to make his first appearance on the celebrity-maker, Saturday Night Live. The Detroit spitter will perform on January 21. It should be a funny one because Aziz Ansari is to host that night.

Though it was already scheduled, Big Sean confirmed his debut as musical guest on Instagram. Last year, Chance The Rapper, Kanye West and Drake made memorable appearances on stage and in sketches. Sean's new album -- an old school concept album centered around the idea of rebirth -- hits stores on February 3. The artist said he wants to "push the culture" and was inspired by Stevie Wonder and Marvin Gaye while working on this project. Sean Don's I Decided. Tour launches in Houston on March 17.
