Prince Harry, third in line to the British throne, donned his finest sunnies and pork pie hat to blend in with the rest of the peasants at London's Secret Garden Party festival last weekend.

The Prince, who often made headlines in the UK for his boozy antics throughout his college years, is still clearly fond of a few pints and some bangin' tunes and that's exactly what he got when he mingled with the 20,000 who attended the festival described by chief organiser Freddie Fellowes as a festival for "professional party-goers", a description which seems to suit Harry to a tee.

We would have expected Harry to have kept a relatively low profile at the festival but some sources have reported that at one point the royal tore off his shirt and partied topless.

He must have gone to the Le Galaxie gig at SGP then...
