Justin Timberlake is prepping for his stint as host and musical guest on 'Saturday Night Live' this weekend with a new teaser video. In it, the 'Suit & Tie' singer and cast member Kenan Thompson poke fun at each other in a series of shorts.

"I don't have my suit and tie. How could I be so stupid!" jokes Justin in one short and storms away. In another, he proves to be a multiple threat by cloning himself into the show's makeup artist, cameraman and sound guy.

This is not JT's first run at the live variety show. He spoofed Ashton Kutcher on 'SNL' in 2003, and premiered his joke tune, 'D--- in a Box' in 2006, when he also performed and hosted.

Watch to see what hilarity Justin brings to 'Saturday Night Live' this weekend at 11:30pm ET on NBC.
