Noirin sparked a furious row after threatening to go on hunger strike.

The Irish housemate told her fellow contestants she would forgo food until Big Brother allowed her to stop drawing on the glasses and moustache she had to sport in order to be allowed into the main house.

Lisa blasted the decision, saying: "I've saw people that are anorexic. I don't want to see my friend not eating. If she's feeling a bit down, like we all are, I don't want to see people encouraging her."

She then clashed with Marcus, who branded the 41-year-old lesbian a "hypocritical bully" and having no respect for anyone.

As Lisa left the group, Marcus began telling the rest of the housemates how much he loved them all, but said he couldn't get on with Lisa.

He added: "I don't think she likes any of us.

"She's come into this house to get back with her ex-girlfriend. We're just obstacles. Everything she's doing in here is false hope. She must be absolutely dying inside."

Charlie disagreed, praising his friend, who soon re-entered the bedroom.

Marcus told her he wouldn't apologise but would always listen to what she had to say and said he thought they could have a lot in common.

Lisa responded with: "Just leave it. You've said what you need to say, so that's it" and left to smoke outside.
