Although 'Britain's Got Talent' has seen a wealth of successful performers appear on its show, that's not the only reason people watch it.
Cowell, David Walliams, Alesha Dixon and Amanda Holden were joined by hosts Ant McPartlin and Dec Donnelly at The London Palladium.
Walliams said he couldn't think of anything better than sitting in a tent with the 'Bake Off' judges eating cake all day.
Rebel Wilson has said the removal of her former flatmate Matt Lucas' show 'Little Britain' from streaming services is 'crazy'.
'Little Britain' has been taken down from multiple on-demand services, with the BBC stating 'times have changed' since it first aired.
Amanda Holden has revealed her gratitude that 'Britain's Got Talent' boss Simon Cowell has kept her on the show, because it 'pays her mortgage'.
