"Here's my SNL promo. Don't laugh," he tweeted, along with the link to the commercial.
The hip-hop artist will be the musical guest on this weekend's edition of the sketch comedy series, while "Scandal" star Kerry Washington serves as guest host.
Eminem appears alongside Washington in the commercial, but only glares at the camera until the actress excitedly tells the audience they are going out for cupcakes after the show and it was the rapper's idea.
"I love cupcakes," Eminem deadpanned.
