Get ready to rock this Saturday (June 18) because the first season finale of Nickelodeon's School of Rock is happening — and Fall Out Boy's Pete Wentz is returning. [Note: MTV and Nickelodeon are both owned by Viacom.]

Wentz will reprise his role as Colton, having previously guest-starred on the show back in March. In "We are the Champions... Maybe," Dewey Finn (Tony Cavalero) and the prep school kids have their song stolen at the Battle of the Bands by a rival band, but then decide an original song might win more points in the long run.

The episode will feature the cast performing WALK THE MOON's "Shut Up and Dance," with Big Time Rush's Kendall Schmidt and Brink!'s Sam Horrigan reprising their roles as Justin and Vince, respectively.

Watch the full clip below.
