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.

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!
