MKTO are returning to Nickelodeon!

Tony Oller and Malcolm Kelly met in 2010 while filming the Nickelodeon television series "Gigantic" and make up the pop duo MKTO. Now, they're making their network return on the series "The Thundermans," and we've got the exclusive pics!

MKTO will be dusting off their acting chops this fall as they perform and guest star as themselves on the live action series, which revolves around the Thunderman twins -- one a superhero and one a super villain.

During the episode, the Thunderman twins, Phoebe (Kira Kosarin) and Max (Jack Griffo) work together to win tickets to an MKTO concert, but a mishap with the paper-shredder at home appears to destroy the tickets, and Phoebe is heartbroken. But Max actually finds the tickets unharmed, yet he isn't sure he wants to tell Phoebe, or take his crush to the concert.

In one of the photos snapped on set the duo appear to be in a diner, acting alongside Kira.

In another shot, MKTO appear to be taking a bit of a break from shooting as they pose alongside Kira and Jack Griffo, who plays Max Thunderman, Phoebe's brother.

MKTO, whose single "Classic" peaked at #21 on the Billboard Hot 100, have a busy few months in store. The two, along with Christina Perri, are hitting the road with Demi Lovato on her very first world tour, which kicks off in September.
