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.

Ant and Dec have been a key part of Santander's promotional campaigns for the past three years and the previous deal is said to be worth £1 million each. PJ and Duncan departed Byker Grove in season five when the characters formed a band and signed a record deal.
Away from the screen, the Geordie presenters actually did sign a deal and released the successful debut album, 'Psyche' still under their Byker Grove pseudonyms. Hits from the recording, which sold over 300,000 copies in the UK, included 'Let's Get Ready to Rhumble', 'If I Give You My Number' and 'Eternal Love'.
Let's Get Ready To Rhumble' was given a second lease of life in 2013, meanwhile, reaching the number one spot in the UK singles chart after the pair performed it on their hit show, Ant and Dec's Saturday Night Takeaway.
