Katy Perry: To appear on 'American Idol' and at King Charles' coronation concert at the same time

How will Katy Perry manage to be in England and America on the same day?

Katy Perry has a very busy schedule.

The 38-year-old singer is expected to take part in the concert for the coronation of King Charles III on Sunday, May 7, at Windsor Castle in England.

On the same day, Katy Perry is also due to appear as a judge on the live show of 'American Idol' in the US, which has many of her fans wondering how she will manage to juggle both commitments.

“You'll just have to tune in and wait and see. The hologram is finally a thing!” the pop singer joked to ET.

Katy Perry is excited about the opportunity to sing during King Charles' coronation celebrations.

“I'm grateful to be able to go. I met the future Her Majesty a few years ago and she anointed me as one of the ambassadors for his organisation, The British Asian Trust, which is an organization that helps fight to end child trafficking,” she said.

“So I'm also a UNICEF ambassador and that really aligns with my values. That's mainly why I'm going, to be an ambassador and say, "Hey, this is me from the US." No, but it's really cool," he continued.

A source recently told ET that Katy Perry has been focused on preparing for her appearance at the King Charles Coronation Concert.

"Katy feels very honored to be performing at the Coronation Concert. She's thrilled," the source said, noting that her fiance, Orlando Bloom, is "supportive."

“She takes good care of herself and is interested in leading a clean lifestyle. She is determined to eat clean, meditate and manage stress better. He's in a good spot," the source added.

Katy Perry also admitted she needs more copies of herself when asked if she'll be attending the Met Gala, which takes place on May 1 in New York.

"I'm going to send Zooey Deschanel in my place," she told ET, joking about her resemblance to the actress.

Katy Perry and Zooey Deschanel have acknowledged and poked fun at their resemblance in the music video for the pop star's song 'Not The End Of The World', which featured the 'New Girl' actress.
