Huge star looks very different as an adorable kid in his first ever TV role

DECLAN Donnelly was barely recognisable in an unearthed clip from Byker Grove in Ant & Dec’s 30 Greatest Moments.

The TV star, 46, was seen as a fresh faced kid tonight in Channel 5’s nostalgic ‘best bits’ show from the Geordie Duo’s career.

Declan played Duncan on the kids’ drama

Dec was just 12 years old when he won a role in hit children’s show Byker Grove, where he met Ant in 1990.

The pair played PJ (Ant) and Duncan (Dec) and their friendship began when they shared storylines on the kids’ drama, creating a bond off-screen as well as on.

The duo then went on to launch a pop career in 1994, known as PJ & Duncan – their characters on Byker Grove.

Their music career didn’t last too long – their record label decided not to renew their contract in 1997.

Having become real-life best friends, their on-screen chemistry proved a winner and they moved into comedy presenting.

And in real life Ant and Dec are inseparable and even used to live on the same street in Chiswick, West London, before Ant divorced his now ex-wife Lisa Armstrong.
