Nikki has confessed to Pete that she feels excluded by the couples in the house.

"I told Big Brother 'I just feel like its a clique - the couple clique', she explained. "And he said 'Do you want to be in the clique?'

"I said 'No!'. But it's, like, getting me down."

Pete - who has apparently decided against a relationship with Lisa - tried to comfort her with little success. "There's no need to pair up with someone," he commented. "It's boring like - being attached."

An unpersuaded Nikki continued, however: "Lea's been quite negative too - worrying about what everyone's saying outside. That's getting me down."

"I've got a lot more depth to me than a lot of people," she added, trying to explain her failure to couple-off. "I know I come across like a scat-brain but..."

"Do you feel a bit rejected?" asked Pete. The model confessed: "Yeah, I do."
