HE had to drink fish guts and brush his teeth with chilli paste while tackling an obstacle course full of goo in a neon-green leotard, but Simon Jobson's determination has paid off.
The 22-year-old DJ from Alnwick will become the voice of Big Brother tomorrow, after winning a competition on the iconic reality TV show's offshoot, Big Brother's Little Brother, at the weekend.
To get to the final, Simon – known as Jobby – first endured a round of maggot-licking whilst blindfolded.
But he made it through and took the title by storm live on Channel 4 on Sunday.
For his efforts, Jobby will be given the celebrity treatment when he arrives at Elstree Studios and the Big Brother House tomorrow.
He will spend the day hanging out with the likes of presenter Davina McCall, before taking a tour of the camera rooms.
But the biggest bonus for the BB-superfan will be to chat to the remaining housemates prior to the evening's live final, when one of them will be crowned winner of the 2009 show.
"I can't actually believe that I am going to be Big Brother for a day," Jobby said. "It's the first time that this has ever happened in the history of Big Brother, so I am quite privileged to be the person that got the opportunity.
"Wearing the green lycra suit was really good fun, although it wasn't very flattering. I had an advantage as the two girls I was competing with were very conscious about their looks, but I didn't give two hoots. My goal was to win, and win I did."
The Big Brother fame effect also rubbed off on Jobby.
"When I left the studio to go to my car, I was on the phone to one of my mates when I heard a group of girls coming towards me," he said. "They noticed who I was and demanded that I had a photo taken. It felt quite strange."
Jobby's voice will be on Big Brother from 8.30pm tomorrow and, before that, on BBLB on E4 from 6pm.
