New BGT judge Simon has proved a hit with the audience and viewers, thanks mainly to his quick witted replies and winding up of boss Simon Cowell.
Speaking of the new comic pairing, David's Little Britain co-star Matt joked: "It's rare to see him on a show with someone camper than him!
"It's good that Simon Cowell's got someone there who will challenge him and tease him. I don't think Simon quite realises what he's let himself in for."
He added: "It's also perfect for David to do. David's achieved so much, not just in comedy, but also acting on stage, in drama.
"I think he should be made a Sir for all the charity stuff he's done. Or at least a Dame."
Britain's Got Talent 2012 continues this Saturday on ITV1 at 8PM.
