TV favourites Ant and Dec returned to their roots for the latest stunt for their new show.

The Geordie duo went undercover as a karaoke loving father and son to set up footballer John Fashanu.

The prank took place in their home city of Newcastle for the new series of Ant and Dec's Saturday Night Takeaway.

Under the assumption he was taking part in Mel Sykes' challenge show, Celebrities Under Pressure, Fash travelled to Newcastle to move in with the Turpins - the family from hell.

Dec played dad Richard, and Ant was his none-too-bright son, Stevie.

The Turpins were karaoke mad, and Fash was given the task to learning the words to every single number one hit there has ever been.

Fash, who became friends with the duo on I'm A Celebrity - Get Me Out of Here, took to the microphone, and even when Ant and Dec gave a performance of their hit Let's Get Ready to Rumble, Fash did not guess who they were.

The duo used a semi-detached house in Gosforth to film the programme

Ant and Dec's Saturday Night Takeaway is on ITV at 7pm on Saturday.
