It's not the first time Katie Hopkins has been in the Big Brother House

This weekend, we cringed behind our cushions as we watched Perez Hilton loudly and publicly attack Katie Hopkins for her field-romping past. Awks!

But as it turns out, that wasn’t the only time the TV motormouth has flashed her cheeks in public.

Shocking images show a then 24-year-old Katie lying face down in the Big Brother House and baring her bum to all, as an unknown person holds their hand above it. But what on this earth was she doing there?

Don’t worry. We haven’t all got amnesia and forgotten an entire season of BB. Who could ever forget Katie, eh?

The ex-Apprentice star actually took part in filming the pilot episode of the show, way back before the first series even aired.

A source told the Daily Star, ‘Katie walked into Celebrity Big Brother last week as though she was new to the experience but in fact she’s done it all before.’

The pictures also show a fresh-faced Katie clutching two bottles of wine, as she cavorts with her housemates. We don’t know who this bum-brandishing-party-Katie is, but we hope she makes an appearance this time round!

The news broke when show narrator Marcus Bentley took to Twitter, telling the world that, ‘Katy [sic] Hopkins was a guinea pig on the first Big Brother!’

We thought guinea pigs were supposed to be cute and cuddly?

Since her ‘curse of kindness’ was lifted on Friday, Katie has managed to upset people inside AND outside the house.

Continuing the vendetta against weight issues that saw her gain almost four stone for TV experiment, My Fat Story, Katie hinted that housemate Nadia Sawalha was overweight, as well as insulting TOWIE’s Gemma Collins.

Never one to shy away from an argument, Gem was quick to defend herself though.

The I’m A Celeb star wrote on Twitter: ‘I swear Katie Hopkins fancies me !! Omg why does she keep going on about me she’s an actual bully keep bringing my name up! Come see me.’

Oo-er! It’s all kicking off in there – and we absolutely love it!

WTF?! Katie Hopkins and Celebrity Big Brother star Casey Batchelor are BFFs now?
