Ever the supportive friend, rocked up at to cheer on his fellow rapper Aitch.
Performing on the Pyramid Stage, got the crowd well and truly going.
He even by bringing out pop star for a surprise cameo.
The 23-year-old cranked up the energy on the main stage of the festival as he rattled through his hit tracks.
Nearing the end of the set, he asked the crowd what their relationship was like with his ex-partners before asking everyone in the field to put their middle fingers up in the air.
He added: ‘My ex is a psycho’, as the chords to his collaboration with Anne-Marie, titled Psycho, were struck up and the singer entered the stage.
Loving all the action from down on the ground was Stormzy himself, who was just the epitome of Glasto joy.
Sporting a cute pair of white heart-shaped sunnies, was well and truly in the thick of it, dancing and singing along with other revellers.
Wearing all the wristbands on his arm and soaking up the heat in a white tank top, the Brit Award winner had his hands in the air and captured moments on video with his phone.
Elsewhere in Aitch’s set, the northern star made time for some playful banter with fans.
In a comical moment, he jokingly called on a security guard to eject a Manchester City fan from the pit.
Mid-set, Aitch – real name Harrison James Armstrong – briefly paused to warn people he was about to ‘upset’ some of them.
Noticing someone in the crowd, he pointed at them and said: ‘You there in the Man City top, you’re not going to like this.’
He then pulled on a Manchester United jersey as the crowd met him with a mix of cheers and boos.
The My G hitmaker then asked security to ‘get him out’ before assuring he was only messing around.
