The British superstars are believed to have been approached to take to the stage at the spectacular party at the Palace for the concert to celebrate Queen Elizabeth II's Platinum Jubilee, but both reportedly declined.
A source told the Daily Mail newspaper's 'Eden Confidential' column: "They were told Adele couldn't. Appointment problems or the like were given as an excuse. It caused big surprises, especially since she was awarded an MBE. Because how many chances will there be of performing for the Queen in front of Buckingham Palace?" A source close to Harry is said to have told the newspaper: "He was asked. He couldn't attend because of the timing with his schedule."
Although Adele and Harry were unable to perform at the concert celebration, a number of stars nonetheless took to the stage outside Buckingham Palace to pay tribute to Queen Elizabeth. Ed Sheeran, Alicia Keys, Duran Duran, Diana Ross and Sam Ryder were among the performers at the two and a half hour event. The Queen opened the event in a pre-recorded clip of her enjoying a cup of tea and a jam sandwich from her purse with Paddington Bear. The duo then began clicking their teaspoons to the rhythm of Queen's song 'We Will Rock You' as the British band and Adam Lambert opened the concert.
