'New housemate' Martin enters the house

The housemates were in for a shock when Keith Lemon sent his friend Martin into the Big Brother house.

The celebrity hijacker had described Martin as a 12-year-old, but the person who entered was a grown man.

"He's got sweaty, clammy hands," warned Keith apologetically as the stunned housemates were introduced to the stranger.

The group soon grilled the newcomer on his age, football team and where he lived, though it was his claim to be staying in the house for the duration of the show that triggered the biggest response.

"Maybe he won a competition to get in here," pondered Victor, while Amy couldn't believe that the housemates were falling for another Big Brother hoax: "He's acting. Don't fall for it again."

"I know he's a character but the guy who's playing it is nervous or the character he's playing is nervous," countered Calista, while John, Emilia and Anthony seemed pleased at Martin's arrival.

Liam was less enthusiastic, revealing: "He's scary, I don't like him. We should all stay in one corner and he can stay in the other corner. It's just the way he looks at you, it's a bit creepy isn't it?"

Martin continued to ingratiate himself with the group as Liam took him on a tour of the house, but the situation soon escalated when a game of kiss chase resulted in a stink bomb being let off.

"Who farted? That's disgusting," said Latoya, as Victor identified the cause of the rotten egg smell.

After a search through Martin's pockets, Emilia found itching powder and soon confiscated it from the newcomer.
