Thornton Heath grime star Stormzy thrilled fans when he held a surprise gig on the same day he released his debut album.

The Croydon-born rapper sang two songs - Big For Your Boots and Shut Up - to rapturous applause in a park in Camden, north London.

Stormzy announced the impromptu London performance on his Twitter account, posting: "Castlehaven Park - Camden - 1PM."

After the gig spoke with fans he took selfies with them.

The grime artist released his new album, Gang Signs And Prayer, at midnight.

The album features a collaboration with Lily Allen, just days after he sang with Ed Sheeran at the Brit Awards on Wednesday.

On Monday, February 13, Stormzy announced that his UK tour had sold out in just four days.

Real name Michael Omari, the star added more events to his 17-date tour after his show in Brixton sold out in four minutes.
