JLS 'tweet' their pecs

It seems to be the latest celebrity craze - tweeting semi-naked pictures.

JB and Aston from JLS are certainly looking good in their 'twitpic' taken during an actual photoshoot.

The picture was posted up by Marvin who wrote,

'What's up peeps how's your Saturday?! The boys and I on a shoot... thought you'd appreciate the pic.'

JB and Aston appear to be chilling out and playing on the Nintendo Wii.
