US pop superstar Katy Perry is set to make a surprise headline appearance at the King's Coronation show - but there is one royal who may have their nose put ever so slightly out of joint by the announcement.
The Duchess of Sussex, Meghan Markle, was previously said to have held a "grudge" against the singing sensation, who once made a critical comment about the former actress's wedding dress.
Ms Perry will perform at the highly-anticipated ceremony concert on May 7 in front of a crowd of 20,000 members of the public and invited guests at Windsor Castle. Take That and Lionel Richie are also among the musical stars who will perform at the Coronation Concert to celebrate the crowning of the King and Queen Consort.
