'I'm done with Frankie Cocozza's sexual harassment and I'll sue Big Brother…' says angry Playboy model Karissa Shannon

Frankie Cocozza has been called a lot of nasty things in his short but colourful career.

However, this is the first time the X Factor reject has ever been accused of sexual harassment on national television by anyone.

The 18-year-old was blasted by Playboy model Karissa Shannon after a booze-fueled argument erupted in the Celebrity Big Brother house.

The trouble began after an excited Denise Welch pulled down Karissa's pyjama bottoms and the American got angry and stormed into the diary room.

After the 22-year-old had vented her frustrations to other housemates she then let Big Brother have it and demanded to be let out of the house.

She shouted: '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,' she added.

Big Brother tried hard to calm down the glamour model but she was infuriated with what had happened and then out of nowhere stated that she was sick of Frankie's sexual advances towards her.

She said: 'I'm done with Frankie's sexual harassment, he sexually harasses me every day, and I want to go home.'

The bombshell came as a shock to viewers who had earlier heard the twin sisters state that Frankie was harmless and he was acting like a typical teenage boy.

The Playmate had, however, been left disgusted by Cocozza's comments to her over the past couple of weeks that have become more and more lewd.

Earlier this week he told the sisters that he wanted to sleep with them and waved condoms at them in the bedroom.

'Come and put a condom on me. Teach me how to do it.'

Frankie was not the only person who was put down by Karissa as the blonde model threatened to take legal action against Big Brother.

She angrily said: '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. 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.

She continued: '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.'

Her sister, Kristina, joined her in the diary room later on and managed to calm her down before telling her that she was 'acting immature'.
