Twins Sam and Amanda Marchant secretly swapped roles in a kinky sex game to see

Lee's seven-month affair with Amanda came to a shuddering halt when he visited a strip club to celebrate his birthday, and she went wild.

"She saw it as a total betrayal," he sighed. "When she found out, she told me, 'I can't believe you went to bed with me just hours after ogling other naked women'."

He only realised the twins were on Big Brother when he received a text from a pal telling him: 'Your ex is on telly'.

"I think Sam will be the flirty one," he said. "She always gave the impression that all it would take to pull her would be to buy her a drink and a kebab. Amanda was the bigger challenge."

Now, as they prance through the C4 house, he is left with memories

"I have to admit it was a turn-on being with Sam for a change," he grinned.

"They both know how to drive men crazy."
