Watchdog presenter Nicky Campbell and Rogue Traders host Matt Allwright have signed up for celebrity duets show, Just The Two Of Us.

The pair will join Holby City actor Mark Moraghan and BBC newsreader Fiona Bruce for the series, which will be fronted by Vernon Kay and Tess Daly. The show unites well-known singers with celebrities who are not known for their musical abilities.

"It's going to be explosive. Before this celebrities have been paired up with relative unknowns for reality shows - this time it will be other stars," a source told the Sunday Mirror. "The singers won't take any excuses. It will be the clash of the titanic egos."
