George and Amal Clooney told fellow guests at Prince Harry and Meghan Markle 's royal wedding that they didn't even know them, it has been claimed.

Hollywood heartthrob George, 59, and his human rights barrister wife Amal, 42, were among the lucky hand-picked guests invited to Windsor Castle in May 2018 to watch the loved-up couple tie the knot.

But it's claimed that the famous pair confessed that they didn't even know the Duke and Duchess of Sussex.

George and Amal had prime seats at the wedding, sitting next to Lady Carolyn Warren, the wife of the Queen's bloodstock adviser John Warren, and opposite Princess Margaret's son Viscount Linley.

George and Amal were at the royal wedding

But according to Rachel Johnson, they told other guests that they were far from best buds with the royals.

Boris Johnson's sister wrote for AirMail : "There’s a story doing the rounds that while Carolyn Bartholomew, Diana’s former flatmate, was waiting for the wedding service to start, she turned to the couple alongside her and asked how they knew Harry or Meghan.

"'We don’t', the Clooneys answered brightly."

Carolyn is Harry's godmother and was one of three young women who shared his late mother Diana's Earl's Court flat and was in on the secret when she first met Prince Charles.

Rachel also claimed that the other celebrity guests at the wedding - such as Oprah Winfrey, David and Victoria Beckham, and James Corden - "could not possibly be old and dear friends of the bridal couple".

Other famous faces at the wedding included Serena Williams and her husband Alexis Ohanian.

Despite the conflicting reports about how well George and Amal knew Harry, 36, and Meghan, 39, it was said at the time that George had been the life of the party, and even danced with both Meghan and Kate Middleton.

Biography Finding Freedom claims that even if the Clooneys didn't know the couple then, they've since grown close and have hosted the Duke and Duchess at their Oxfordshire home on at least two occasions.

It says that Meghan and Harry would take their dogs with them and that George and Amal would take their friends out by the lake.

Did George and Amal know the couple then?

It's also claimed that Harry and Meghan were flown out to Lake Como on George's private jet to join him and his wife just weeks after the wedding.

A source said at the time: "Meghan and Amal spent a lot of time relaxing by the pool and playing with the twins while George and Harry checked out George's motorbike collection. Harry took one of them out with one of his protection officers. George recently had an accident, so he wasn't back on his bike yet."

Mirror Online has contacted representatives for both couples for comment.
