The 'Lego House' singer joined the musical comedian on stage recently for a duet about prejudice against people with ginger hair.
Ed Sheeran surprised fans at London's Apollo theatre recently when he joined comedian Tim Minchin on stage for an impromptu duet.
The 'A Team' singer-songwriter was welcomed on stage by the Australian comedy star during a performance of his song 'Prejudice' in late December.
The song they performed tells of the prejudice faced by people who have ginger hair, with both Ed and Tim notably sporting the hair colour.
Ed Sheeran is currently in America recording a secret project he has promised will make fans go "nuts" when they hear it.
