Londoners were treated to an inpromptu performance from the global superstar as he settled down to busk with his guitar near Buckingham Palace.
Justin Bieber is currently in London with fiancee (and rumoured wife) Hailey Baldwin. Justin was supporting Hailey at London Fashion Week and the pair seem to have been taking the opportunity to fit some sightseeing in as they've since been spotted near the London Eye and in Hyde Park.
Some fans are even wondering if their stay in London is the couple's honeymoon - as there are rumours that they secretly married after being spotted in a New York Courthouse last week.
Now, several lucky passers-by have been treated to an inpromptu concert as the star got out his acoustic guitar to serenade Hailey in the street near Buckingham Palace. Justin sang acoustic versions of his own 2016 hit Cold Water and Tracy Chapman's Fast Car, with fans quick to upload footage of his busking to social media - watch the video above to see him in action!
