Katy Perry lit up King Charles and Queen Camilla's Coronation concert like a firework in a dazzling golden gown and her beau Orlando Bloom couldn't be prouder.
The American songstress, 38, took to the stage at Windsor Castle on Sunday evening wearing a glamorous Vivienne Westwood dress and wowed the 20,000-strong crowd with an energetic performance.
Her Pirates of the Caribbean man has since taken to Instagram to share his delight at her performance, gushing: "Immensely proud of you my love. You always bring the light."
Katy cutely commented back: "Our light," with a heart icon.
Orlando's post showed the stunning venue lit up with a lion firework in one image, while another showed the American Idol judge with a beaming smile with the microphone in her hand.
Katy began her performance by telling the crowd: "I'm so happy to celebrate this whole weekend. I got to bring my mom. She is so happy to be here. We get to stay in Windsor Castle. No big deal."
And as fans screamed in delight, a special moment was later captured on camera as Princess Charlotte was spotted singing away to Katy's songs.
The eight-year-old daughter of Prince William, 40, and Princess Kate, 41, appeared to thoroughly enjoy the rendition of the hit single Roar at the lavish event.
However, while the performance went down a storm, some fans were less than kind when it came to describing the flamboyant outfit.
The shimmering gold princess-style outfit with a low cut front dazzled under the bright lights and some joked she had come as a "British icon" - a Quality Street sweet.
Others thought it more resembled the wrapper from a Ferrero Rocher. One Reddit user jibed: "Katy Perry’s dress at the Coronation Concert was fabulous.
"Shoutout to all those who stayed up glueing the Ferrero Rocher wrappers together!"
Another questioned: "Why's she wearing a Ferrero Rocher wrapper?"
The view certainly wasn't shared by everyone, though and some fans described it as a "stunning" look.
After Katy shared a snap of her hugging her mum after the concert, Kris Jenner gushed: "Wow!!!! Soooo beautiful!!!"
And the Royal Family's official Instagram page applauded her routine, writing: "Thank you for a fantastic performance at the #CoronationConcert!"
