Speaking on tonight's show, the music mogul declares: "I’m on a mission to find a dog act. We want to find the best"
And when 16-year-old schoolgirl Ashleigh walks on with her pet pooch, the telly chief's eyes light up.
Ashleigh reveals to the panel how she was given her dog as a present six years ago on her eleventh birthday: "He was in a little box all wrapped up.
“Me and Pudsey have an amazing bond, I walk him, feed him, groom him... I do everything with him."
The youngster - who apparently loves her dog more than boys - adds: "I’ve come on Britain’s Got Talent because I know Simon has been looking for a new Lasie for quite a while, and I hope Pudsey can fill those boots.”
On stage and Simon asks the pair: "Do you think your dog and you can win an Oscar?"
A confident Ashleigh replies: "yes."
The pair go on to dance to the Flintstones theme tune, but will Simon be impressed?
