What do you like to pig out on?
''I had a massive pig out last night on those tubs of mini flapjacks from Marks & Spencer- they're amazing.''

The body's pur boy- but Gaz sure has a girl's appetite!
SIN 6: SLOTH
How lazy are you?
''Not at all Lazy. I have to be up at 6:30am every day and I never get time off! I wouldn't spend the whole day in my PJs anyway- I like to sleep commando!''
What would your friends say you're lazy about?
''Texts. I can't be bothered to write whole words- even though my phone translates your handwriting into typing!''

Gareth's got too much get-up-and-go to be really rock 'n' roll.
SIN 7: ENVY
What makes you envious?
''I envy my mates back home. It's just small things, like how they can go shopping or clubbingg. I can't 'cause I'd get mobbed, and the press write about me every time I go out.''
Do you ever get jealous over girls?
''Yeah. Especially when I was younger- I used to get really jealouss when my girlfriends talked to other boys. But only because it hurt so much inside.''

THE VERDICT
So is Gareth a hotel-trashing animal or a sensitive soul?
With a grand total of 23/35, the jury's still out. But when bliss listens back to the interview tape, we discover that Gareth has left this goodbye message. ''Hi bliss girls- this is for you...'' and there follows the longest, loudest, most revolting burp we've ever heard.
Rock 'n' Roll? You betcha!
