Royal Children Steal the Show at King's Coronation Concert

Katy Perry performed at King Charles III's coronation concert at Windsor Castle, with Princess Charlotte singing along to "Roar." Perry thanked the new king and queen for allowing her to be there and for the work she's done on behalf of the British Asian Trust. Fellow American Idol judge Lionel Richie also performed. The concert followed the official coronation ceremony at Westminster Abbey, where Charles was crowned king and Camilla Parker Bowles was anointed and crowned as queen. Prince Harry attended the coronation, but Meghan Markle did not.
