It seems that batteries and fizzy water were the reason...


...that X Factor finalists Olly Murs and Joe McElderry snuck out of the X Factor house in London on Wednesday night at 9pm, and broke their 8.30p.m. curfew!

Here's the photographic evidence:

Yes, Joe you have been spotted breaking your curfew - were you really that desperate for a bottle of sparkling water?!

They know they've been rumbled!

Apparently Olly was wearing a woolly hat his grandma made for him - bless!

Aww - signing autographs made Olly even later!

What do you think their punishment will be - a bowl of Jedward noodles?! Ironing all of Simon's high-waisted trousers, perhaps?!

Comments please!
