Gareth Thomas has admitted that things got very out of hand during the big row in Celebrity Big Brother last week.

In scenes not aired on the Channel 5 show, the rugby star stayed with Denise Welch to protect her against Karissa and Kristina Shannon and Nicola McLean, who were furious after she pulled down one of the twins’ trousers.

Thomas admitted that Big Brother bosses locked him and Denise in one room and the three screaming blondes in another, after it looked like things may turn violent.

He told The Daily Star:

“The twins came running to the door and Big Brother locked it just before the girls got to it.”

“That’s when I told Denise I’d have to sit with her because I wasn’t having them going at her.”

Gareth also admitted that he got a little claustrophobic in the house and struggled with the monotonous routine. He added:

“I struggled in there. I was climbing the walls. The boredom and downtime was a nightmare. It was slowly killing me. I had to watch it when I started to get pissed off with everyone around me.”
