We know Simon Cowell is Simon Cowell's biggest fan. But is he Simon Cowell's biggest fan?

OK, we'll explain. On this weekend's episode of Britain's Got Talent, a 47-year-old IT analyst comes along to audition. His name, much to the amusement of Amanda Holden, is Simon Cowell. 

A sidenote, but check out Ant's cackle. It almost rivals Amanda's!

Anyway, after some rather intense preparation, Simon is ready to go. But what is his act? You'll have to watch the video above to find out.

Britain's Got Talent airs at 8pm on Saturday 22 April on ITV
