'The tables have finally turned!': Ex-prostitute Helen Wood breaks down as she meets her match in Big Brother's Nikki Grahame and Aisleyne Horgan-Wallace

It had all the makings of a perfect storm.

And, inevitably, tensions between former prostitute Helen Wood and glamour model Aisleyne Horgan-Wallace reached thunderous proportions on Thursday's episode of Big Brother.

The fever pitch comes just hours after the pair were unwillingly reunited in the Channel 5 reality TV series - with Nikki Grahame in the middle.

But, despite a relatively civil start, tensions between them soon fired up.

As it gathered pace, Helen then took Marc into the toilet for a debrief and said: 'I know what a game is and she's going to try and turn everybody against me. So that's why I need to keep away from that b**ch.

'People have already told me that you're going to swap me for her, but you do what you want. I don't need anyone.'

As the fight escalated, Nikki directly told Helen - with a full audience - that she single-handedly bullied Brian out of the house.

'Remind me: when were you a legend in BB? Who are you? You're a hated figure,' Nikki yelled, while Helen was left standing alone, undefended.

'Brian is a good person - as am I. Together, we are good people, which is something you can't ever be. You're just vile. You were born vile. You're pure poison.'

Naturally, Helen couldn't resist wading into the fight and being even more aggressive.

'I can't believe I'm being told this by a Z-list celebrity. Who the hell does she think she is?' Helen barked, to which Nikki replied: 'Well, if I'm Z-list then you're unclassified.'   

Sparking laughter from the other tenants, the sea change clearly got to Helen - especially when Danny sided against her. 

Be told! 'I can't believe I'm being told this by a Z-list celebrity. Who the hell does she think she is?' Helen barked, to which Nikki replied: 'Well, if I'm Z-list then you're unclassified.'

Losing her cool, Helen's hard-faced attitude soon dissolved after she had a taste of her own medicine. Out-numbered with Nikki and Aisleyne joining forces, she burst into tears in full view of her housemates.  

As Sam told her not to get upset, she snapped back: 'I'm not upset - I'm f--king angry,' before throwing a glass across the room and storming off, adding: 'I just want to be on my own.'

At that point Danny said: 'I'm so glad this has happened.'

Walking into the bedroom, Helen could be heard shouting: 'I can't do anything right in this f--king house', before being followed in by Marc.

'I can't believe I just lost it in there,' she added, crying. I promised I wouldn't get upset by that professional slag'. 

Later, she said: 'I don't mind how long she's here for - as long as she stays away from me.'

But, by that point, Marc was already started to worry about his association with the former prostitute. Marc confessed he was worried the public would turn against him after his part in Brian leaving the house.

Supportive: 'Aisleyne was quick to praise her pal, who has clearly felt stronger since her arrival. 'You stood up to a bully and I'm really proud of you for it.'

'Helen's not a legend. She's a bell-end.'

But Aisleyne was quick to praised her pal, who has clearly felt stronger since her arrival. 'You stood up to a bully and I'm really proud of you for it.'
