Anthony Joshua was able to live his teenage dream after performing 21 Seconds alongside So Solid Crew at a packed out nightclub.
The British heavyweight, who will take on Kubrat Pulev next in London, was filmed at Garage Nation – and impressed the capacity crowd by rapping along to the former UK No 1.
Joshua is set for a busy year, with the 30-year-old ordered by the WBO to fight both Pulev and mandatory challenger Oleksandr Usyk.
But the two-time unified champion took time out of his preparation to make a surprise appearance at the popular event.
Joshua took to the stage with Lisa Maffia, who is widely known as being the main female member of So Solid Crew, and put on a very different kind of show for the hundreds packed into the venue.
The event later took to Twitter to rave about Joshua’s shock cameo, and described the performance as ‘one of the best moments in Garage Nation history’.
