The Crown fans were stunned on Tuesday evening when Emma Corrin made a surprise appearance at the 2022 BRIT Awards.
Emma, 26, looked completely different from their character on the hit Netflix series and took to the stage to recite a verse during Little Simz's single "Introvert".
Emma appeared halfway through the set wearing a huge white hat with a matching blazer and black trousers.
Worlds away from their role as Princess Diana in The Crown, their hair was pulled into a middle parting with exposed roots coming through under the dyed blonde.
Viewers tuning in at home were shocked to see Emma on stage and took to Twitter to comment.
Many viewers were baffled by Emma's random appearance, with some saying they had to "do a double take".
One person asked: "Was that Emma Corrin?"
Another chimed: "Emma Corrin at the Brits tonight!!!”
"Did Emma Corrin just appear at the Brits??!!??” added another viewer.
“Little Simz is iconic. Emma Corrin as well?? My eyes are blessed," said another delighted fan.
Emma's spoken verse also appears on Little Simz's album 'Sometimes I Might Be Introvert'.
The rapper told i-D last year: "I think Emma Corrin is amazing man. She’s really really talented and just a beautiful, genuine, nice soul.
"Getting her on the record, I just knew that her adding her magic would take it somewhere else, she just has a great voice."
Little Simz, who was nominated for the Artist of the Year Award, wore a Prada suit complete with crisp white shirt and a black tie.
She performed a medley of Introvert and Woman at 2022 BRIT Awards and won the Best New Artist accolade.
Little Simz, real name Simbiatu Abisola Abiola Ajikawo, took her mother up onstage with her to collect the gong and easily gave one of the best speeches of the night.
