David Walliams horrified as Simon Cowell tricks him into handing over £1,000 cash when he loses hilarious Britain’s Got More Talent challenge

DAVID Walliams was left horrified after Simon Cowell tricked him into handing over £1,000 cash.
It all happened when the comedian, 47, lost out on a hilarious Britain's Got More Talent prank.
The challenge involved not being able to say the "number 17" - if you said this number you lost.
First of all Britain's Got More Talent host Stephen Mulhern played the prank on Simon, which saw him ask Simon the answer to a number of sums, without saying 17.
The last sum was "what is 10 minus three?" - to which Simon replied "seven".
Stephen then quickly replied, "Thanking you!" - to signal that Simon lost the joke, which of course he hadn't, so Simon said, "But you said 17!" - which was in fact the joke, as Stephen had got him to say 17. Keeping up? Good.
Simon loved the joke so much he wanted to play it on David - and even bet him £1,000 that he would lose.
However, the prank did not go down too well with Mr Walliams, who looked less than impressed when he fell for the joke.
Simon couldn't contain his excitement at making David look stupid, and jumped up in the air shouting: "You owe me a grand!"
To which David replied: "I haven't got in on me, but I'll give it you, cause you need more money don't you!"
The show was a tease to get fans excited about the return of Britain's Got Talent tonight.
The show will also see Ant McPartlin's big TV comeback.
Ant returned to hosting duties on the beloved talent show with Declan Donnelly this year after his pal presented the last instalment solo in the wake of his drink and prescription drugs battle.
And viewers will see it's not the only the judges who missed his presence on the series during tonight's season premiere.
The BGT judges are reduced to tears by the joyful kids' audition while Ant is left welling up after a young girl says she "missed him" on the entertainment show.
The moment is a real tearjerker as Flakefleet Primary School, from Fleetwood, Lancs, perform Queen's Don't Stop Me Now led by headteacher Dave McPartlin, who is of no relation Ant.
After the children bring the house down, judge David Walliams says: "You made our hearts soar. It's one of the most joyous things I've ever seen.
"This is what you want your childhood to have been like – and what you want your children's childhood to be like."
As the kids leave the stage Ant picks up a girl called Emily and jokes: "Right. I'm keeping one."
Hugging him tightly, she says: "I missed you."
The emotional star says he "loves her lots" when she eventually lets go.
Watch Britain's Got More Talent, Saturday 6th April from 8:35pm on ITV 2
