Ant McPartlin and Declan Donnelly have reprised their roles as PJ and Duncan.
The popular presenters shot to stardom as the characters in children's programme Byker Grove. Ant and Dec played PJ and Duncan until 1993, but are set to return to their teenage roles for a Santander advert.
Mirror Online report the deal is worth around £2 milllion to the presenters. They have been spotted in PJ and Duncan's trademark baggy clothing with baseball caps and matching backpacks as they rode branded bikes in London.
