Stormzy has helped to redecorate a teenage boy's bedroom as a reward for the youngster's good behaviour at school

The rapper, who now lives in New Malden, worked on the project with The Good Guys firm in Croydon, close to where he grew up.

The schoolboy wasn't aware the Glastonbury headliner helped to transform his room until he got home from school and Stormzy surprised him by opening the front door.
