The Queen, Prince Philip and US First Lady Michelle Obama allegedly enjoyed a three way sex romp whilst US president Barack Obama was busy at the G20 summit, I can exclusively reveal.
Mrs Obama agreed to take part in a "marmite sandwich" with the love-struck royals whilst her husband was otherwise engaged with the leaders of the world's largest economies, palace insiders say.
At a subsequent official reception the Queen and Mrs Obama were said to be "all over each other like a cheap Japanese suit," by reporters.
"They are obviously very much in love," one insider who refused to be named revealed.
"Considering that you aren't even supposed to touch the Queen, let alone straddle her armed with a strap-on, I'm shocked quite frankly," said a Palace prude.
Well-wishers outside Buckingham Palace waved flags and sang the Paul McCartney classic "Ebony On Ivory" until well into the night.
