The schoolgirl has already made over £1 million in performances since winning the show earlier this year, and returned to the stage where it all began for the gameshow.
BGT hosts Ant and Dec were also there, hosting the Simon Cowell game show.
Suddenly it's no surprise to see Ashleigh and Pudsey there...
The pair will be performing a new routine as part of one of the show's wacky Red or Black games.
Also on this Saturday's show, snooker players Judd Trump and Neil Robertson go head to head, and international lumberjacks scale dangerous heights.
Red or Black airs at 7:25PM on Saturday night on ITV1.
