TOP Hartlepool dance group Ruff Diamond are set to show off their moves on national television again when they appear on Blue Peter this week.
The lads will perform a show-stopping routine on the television institution when the programme airs tomorrow teatime.
Also due to star alongside the UK hip-hop champions is adventurer and Chief Scout Bear Grylls who will show young viewers how to build a den.
It will not be the first time that Ruff Diamond have appeared on the BBC.
Last year they were watched by millions of viewers after they performed a routine with the cast of EastEnders as part of the Children In Need Appeal.
The lads will film the show at the BBC’s new headquarters in Manchester.
Ruff Diamond have enjoyed a lot of attention since they were runners-up in the Sky 1 competition Got To Dance.
They went on to open the BBC Radio 1 Teen Awards last November.
Blue Peter is on CBBC at 5.30pm tomorrow.
