Katie Hopkins was guinea pig on first ever Big Brother and flashed her bum in the house

These days Katie Hopkins is famous for blabbing her mouth off about anything and everything.

But she’s been suspiciously nice in the Celebrity Big Brother house even though her task to be as friendly towards her fellow housemates as possible as now ended.

Considering she’s so proud of her straight talking persona having turned it into an actual brand, you might think she’d have almost KILLED some of the other cast with her evil comments, but no.

Why could this be? Is it because Katie always dreamed of being on Big Brother? It certainly seems that way! The former Apprentice contestant was a guinea pig for the pilot of the civilian version of the show 15 years ago and was shown round the house before the original series even aired.

Producers tested everything out to make sure it was all running smoothly before the first season started in 2000 - and needed guinea pig contestants.

And she was so desperate to make a lasting impression she even flashed her bum while another of the volunteers patted her, er, cheeks. Wow.

Big Brother voiceover legend Marcus Bentley broke the news on Twitter, writing: “Katy Hopkins was a guinea pig on the first ever Big Brother!”

Katie was set a task to be nice to her fellow housemates after entering the house but once the challenge ended, she failed to unleash her acid tongue in the same way she does in the outside world.

Perhaps she’s hoping to fulfil her dream of staying in Celebrity Big Brother for as long as possible...
