The 33-year-old royal and the 36-year-old actress will tie the knot at St George's Chapel in Windsor Castle on Saturday (19.05.18), and people across the world will be tuning in to enjoy the celebrations.

Holly, 37, was revealed her own plans for the big day are combined with her sister Kelly's 40th birthday - and they've had an interesting idea.

Speaking on 'This Morning Live' yesterday (17.05.18), the presenter - who married producer Dan Baldwin in 2007 - said: "It's my sister's 40th on the same day so I've got a big party for her birthday anyway, all day, and then obviously the royal wedding, so extra excitement.

"And then this week on the old family Whatsapp group that we all have, my sister Kelly said, 'I've got an amazing idea - for anyone that's been married go and get your wedding dress and wear it to the party.' "

While Holly is happy to don her gown to mark Prince Harry's marriage to Meghan this weekend, she admitted it wasn't in any condition to be worn when she first brought it out of storage.

She added: "I dug it out - I took it into 'This Morning' to the big steamer as I haven't got one of those. It is filthy! I haven't had it dried cleaned. It's a bit ripped. I will look a bit like Miss Havisham.'
