Chaos in Big Brother house

It's all kicking off with this year's celebrities...

09:55 24 January 2012

Karissa Shannon has threatened to sue Big Brother after Denise Welch jokingly pulled down her pants on the reality show.

The tears began after Loose Women's Denise partially exposed Karissa's bottom after Big Brother played music into the house.

Afterwards, the Playboy model, who has two sex tapes, told Denise:

"I'll forgive you tomorrow but I'm p***ed off."

Later in the Diary Room, an emotional Karissa - who had been drinking wine during their 'girls night in' - said:

"I want to leave. I'm ready to go now, I wanna go home. Denise just tried to pull down my pants for no reason.

"She knows I'm one of the most reserved people in the house, I'm the classy woman of the house. I do not do that type of stuff.

"You're gonna show my ass on TV, that's for sure. I'm not cool with that so I'm going to sue you guys. I don't flash my a**, or flash my t**s, I feel disrespected."

She then added her threats to sue the show:

"My management's not gonna be OK with this, and I know you guys roll your cameras 24 hours a day, and I know you got that shot. You're going to show that, and I'm going to sue you for it, so I want to leave now.

"I'm serious. This isn't some stupid s**t. I'm p***ed off."

The incident then lead to a house-wide argument between the remaining girls, with Nicola McClean and Denise both declaring that they wanted to leave the house.

Celebrity Big Brother continues tonight at 10pm on Channel Five.
