Lee RyanWhose finger offence?We can only apologise.

Some celebs just can't help themselves these days.

But this young man didn't strike us as the swearing type.

We're shocked, surprised and more than a little let down, quite frankly.

But perhaps we would be swearing too, if we found ourselves backstage at a gig in Manchester with nowt to do.

Luckily, the celeb seen here soon cured his boredom.

With a spot of washing - though not of the conventional shower 'n' suds kind.
