Big Brother housemates reunite for E4′s Big Brother quiz tonight and admit that they all share a common bond.

Glyn Wise, Charley Uchea and Brian Belo admit that they are never stuck for conversation topics when they meet other former housemates, even ones that entered the house on different series.

“Obviously we go into the room and it’s like a topic of conversation ‘so did you enjoy Big Brother?’” said Glyn, who was the runner up of Big Brother 7.

He also joked: “Some of them you look at and you think ‘ugh’, but there is that bond.”

Charley – a housemate from Big Brother 8 – added: “We do (share a bond) because we’ve all lived in the house and we know what it’s like, if you don’t and you tell a story no one really understands what you’re going on about.”

Big Brother 8 winner Brian Belo said he has a respect for all ex-housemates:

“Even people you don’t get on with, there’s definitely sort of a mutual respect there because you think to yourself you’ve lived it in that house and you’ve lived it afterwards and you sort of know what the drill is,” said Brian. “For that I think you always have a mutual respect with people who have been on Big Brother.”

Big Brother’s Big Quiz is on tonight at 10pm on E4.
