Sarah Harding is so beautiful. I'm absolutely gutted that she has passed. Lovely lady and gorgeous xxxx

God this is depressing; they seem like they used to be pretty good friends.

They knew what was going on from the start

Even as a kid back when these older episodes first went out, I could see straight through the crap make-up they had for the Undercover bits. Pretty sure most of the celebrities knew who they were instantly too and just played along for the show.

5:59 Cheryl so fit

you can tell some of them knew early on it was them kind off

R.I.P Sarah Harding
