Los Angeles, Feb 20 : Singers Adele and Ed Sheeran have declined the offer to perform at King Charles' coronation concert.

Rumor has it that both the stars have turned down the opportunity due to their ‘busy’ schedules.  The King is set to be crowned on May 7 at Westminster Abbey, with a later event being held at Windsor Castle.  The Mail on Sunday reported that the Easy On Me songstress and the Perfect crooner were asked to perform after the monarch discussed with organisers his hopes that they would appear.  A source revealed, “The King has suggested a number of people he would like to perform and Adele and Ed were on that list. He was very keen that they were part of the concert.”  The insider further revealed, “There is a team set up to get the talent signed up so they approached the two of them, but got replies saying that they were unavailable, which was a massive disappointment.”
