Don’t forget your Umbrella, ella, ella, at the Hackney Weekend as Rihanna set to perform

The Hackney Weekend has become a mud bath overnight, and wellies have become an essential festival fashion-item on the festival’s second and final day.

Many pop-lovers donned wellies with shorts on the Radio 1 festival’s opening day yesterday.

But boots were not really necessary, as the ground remained dry with just a splutter of rain as Jay Z’s set began at 10pm.

But heavy rain over night has created muddy puddles and slippery stages as Plan B discovered to his peril earlier, as he slipped several times.

However the strange weather meant crowds are alternating between rain jackets and umbrellas and sun hats and glasses – and back again.
