Simon Cowell and the BGT judges arrive in London - by tube!

Simon Cowell, Amanda Holden, David Walliams and Alesha Dixon arrived at The Palladium in London today for the first day of Britain's Got Talent London auditions.

 Who would have thought we would see Simon Cowell on the London Tube?

They were running behind schedule but Simon still made time for the fans who had been waiting for hours.

 Amanda Holden and Alesha Dixon glammed up.

Good to see Dec in fine form

Loving Amanda Holden's dress!

We can hear that famous laugh from here Alesha Dixon!
