Taylor Swift received offer to perform at Coronation of King Charles III but turned it down, claims new book

Taylor Swift passed on an offer to perform at the coronation of King Charles III.

The 33-year-old songstress declined an offer to sing at the coronation this past May in London, according to the new book Endgame: Inside the Royal Family and the Monarchy's Fight for Survival from author Omid Scobie.

The Grammy-winner was in the midst of her The Eras tour, playing multiple dates at Nashville's Nissan Stadium May 5-7, with the coronation taking place May 6.

The Look What You Made Me Do performer was not the only notable name to pass on playing at the coronation, Scobie said in the book, adding that it was 'a challenge' to put together a show for the coronation concert.

Elton John, 76, passed on playing the show due to scheduling issues, his rep told US Weekly, adding that other entertainers who were reported as having passed on performing at the event included the Spice Girls, Harry Styles and Adele.

Among the entertainers who did perform at the event included Katy Perry, Lionel Richie, Andrea Bocelli and Take That.

Ahead of the show in April, Perry said she was 'grateful' she was attending the event, in an interview with Entertainment Tonight.

She told the outlet: 'I met His-Majesty-to-be a few years ago, and he named me as one of the ambassadors to his organization, The British Asian Trust, which is an organization that helps fight to end child trafficking.

'So, I'm also an ambassador for UNICEF, and it really aligned with my values. That's mostly why I'm going, to be an ambassador and to say, "Hey, this is me from the USA." No, but it's so cool.'

Richie, 74, told the outlet of his participation: 'To be in this part of history, I'm just blown away, I'm so excited to be there. I'm walking in history.'

Meghan Markle, the Duchess of Sussex, 42, was in attendance at the Shake It Off singer's August 8 show in Los Angeles at SoFi Stadium. Prince Harry, 39, was away at the time on business in Asia, according to US.

Endgame: Inside the Royal Family and the Monarchy's Fight for Survival is slated to be released Tuesday.

Dailymail.com has reached out to Swift's reps for comment on the story. 

Swift on Monday announced her hit The Eras Tour movie will be coming to streaming services next month.

The Anti-Hero singer - who invited the family of Ana Clara Benevides Machado to her show in Sao Paolo - revealed her tour movie will drop as an extended version with three extra songs.

She wrote: 'Hi! Well, so, basically I have a birthday coming up and I was thinking a fun way to celebrate the year we've had together would be to make The Eras Tour Concert Film available for you to watch at home!' she wrote. 

'Very happy to be able to tell you that the extended version of the film including Wildest Dreams, The Archer and Long Live will be available to rent on demand in the US, Canada & additional countries to be announced soon starting on … you guessed it, December 13.' 

December 13 is the All Too Well singer's 34th birthday.  

The news of the concert film debuting on demand for at home viewing comes as the Shake it Off singer wrapped her global, record-breaking, Eras tour in Brazil on Sunday night. 

The Taylor Swift: Eras Tour movie also set records during its limited run in AMC theaters.

It is the top-grossing concert film of all time in North America and was the first one in history to make more than $100 million domestically as well as the first independently released film to hit that mark in just two weekends in a decade.

Swift self-financed the film which has grossed more than $165 million in the U.S. The movie was filmed over the course of three of the Bad Blood hitmaker's shows at SoFi Stadium in Los Angeles.

With the three songs added to the extended version of the movie, that leaves just two songs from her original set lists that are still missing: Cardigan and No Body, No Crime.

Fans responded ecstatically to the news in the comments of the Grammy winner's post with many of them asking why Cardigan was left off the list.

One fan wrote: 'Taylor said “Time for in home therapy swifties,"' while another said: 'OMGGGGG!!! Cant wait to rewatch 20 times!! Only Tay gives presents to Swifties on HER own birthday!!'

Another fan reacted very enthusiastically, writing: 'ARE YOU KIDDING ME OMG I AM SCREAMING!!!! I’LL BE WATCHING THE ERAS TOUR FILM 24/7 STARTING DECEMBER 13TH.' 

And finally one fan summed up what all Swifties are feeling with this news: 'I need to calm down.'
