Sadly though it looks like it's all good natured "horseplay."

Look at their cheery faces! Still, we're sure a couple of those "jokey" punches must have had a bit of heft behind them. You wouldn't be able to stop yourself would you? Ka-pow! Poor old Johnny's got a face you'd never tire of smacking...

He kept things "real" by rounding his antics off with a trip to Tesco's for a snack, where the lady at the checkout kicked him in the nuts and told him all his songs are shit.

Not really :(
