King Charles' Coronation weekend will see a string of celebrations take place across the UK.
And one event that pop music fans will no doubt be looking forward to is the Coronation Concert, set to take place on May 7 at Windsor Castle.
A host of acts are being lined up for the show, which also includes performances from a huge orchestra and the Coronation choir.
The full list of acts taking part has yet to be confirmed - but rumours have swirled that the Spice Girls could reunite for the big gig.
If they did, Charles would be no stranger to Baby, Sporty, Ginger, Scary and Posh after a somewhat chaotic first meeting with the girls in 1997.
Archie and Lilibet's titles 'need to be earned' by Harry and Meghan, says sourceThe then Prince of Wales got more than he bargained for after they attended a Princes Trust dinner, with Mel B and Geri even giving him a kiss on the cheek.
Geri even told him that he was "very sexy" and allegedly touched the future King's bum - with many at the time reporting that she gave his bottom a pinch.
The singers did their "girl power" symbol by making a peace sign, which appeared to baffle Charles.
He asked them: "What's all this business?" as the girls urged him to join in with the pose.
But he turned down their cheeky request even after they explained that it stood for "people power" and asked: "You do believe in that, don't you?"
Years later, Geri would deny that she pinched Charles' behind and insisted it was only a "pat".
"I didn’t pinch Prince Charles' bum, as was reported. I patted it," she insisted. "Patting him on the bottom was against royal protocol but we're all human.
"There was a lot of nervous energy, young women, happy antics."
Thankfully, Charles clearly saw the funny side as he ended up bringing one of his sons to meet the girl group in November 1997.
The King and Prince Harry met the Spice Girls along with Nelson Mandela in South Africa. He later took both Harry and Prince William to the premiere of Spice World the movie.

"He's a modern man, he's a modern royal in everything he does. He has consciousness. He thinks about the world that we live in."
