Ruthie Henshall boasts about X-rated Prince Edward bedroom action in Buckingham Palace

I'm A Celebrity star Ruthie Henshall opened up about her romance with Prince Edward on the show last week and bragged about "s**gging" at Buckingham Palace.

During Friday night's episode of the hit ITV show, West End star Ruthie made a steamy revelation about her romance with the royal.

Ruthie, 53, dated the Earl of Wessex for five years in the early 1990s and came clean about her connections to her campmates.

Actor/singer Shane Richie told the campmates how he "performed at the Palace during lockdown".

Fellow celeb Ruthie walked past him and dropped a bombshell, stating: "You performed in Buckingham Palace, you sang in the gardens, I shagged in the bedrooms."

She went on to reveal she was introduced to the Queen during her romance with the prince, but accidentally broke protocol by shaking the monarch's hand.

The star told Shane: "He invited me to Windsor for the weekend and as we're walking I'm seeing a table outside and there's people sitting around it and I'm thinking: 'That looks like the Queen'.

"I remembered my dad had said to me that if you ever meet the Queen he said you curtsy and call her ma'am.

"But I grab her hand, forget all about the curtsy, and I'm like: 'I'm really, really pleased to meet you!'"

Royal protocol generally dictates that women should curtsy when meeting a member of the royal family, while men are expected to bow their heads.

After she made the revelation about her saucy antics at Buckingham Palace, Lady Colin Campbell pointed out her error on IAC spin-off the Daily Drop on Saturday.

She explained Ruthie had broken a number of strict royal protocols in her meetings with senior members of the royal family.

Blasting Ruthie for "shaking hands" with the Queen, Lady C scolded: "She should have said your majesty, curtsied then 'ma'am' thereafter."

She also explained how Ruthie ended up bedding the royal at the palace, adding: "That's because he lived there.

"He had his own suite of rooms there. They live there, they can do pretty much what they want."
