Ed Sheeran almost had his head cut off during a prank knighting ceremony with Princess Beatrice.

Well, maybe not cut clean off, but he did sustain a cut to the face as the seventh in line to the throne pretended to knight fellow crooner James Blunt with a real sword at a raucous party.

I See Fire singer Ed, 25, was rushed to hospital after Bea, 28, swished a sword around during a party prank without checking who was stood behind her.

The singer needed stitches – but then apparently went back to the party despite it being the place he got literally stabbed in the face at.

You’re a braver man than us, Ed.

Ed was at a party with Princess Bea, Blunty, and a number of others when You’re Beautiful singer James joked he’d love to receive a knighthood.

“Beatrice jokingly said she could arrange it and fetched a ceremonial sword,” an eyewitness told The Sun.

“James played along with the prank and got down on one knee as he would if he were at Buckingham Palace being honoured by The Queen,” they continued.

“Beatrice, who was in great form, held the sword above him and said ‘arise Sir James’… But she must have misjudged the weight or something and she swung it back, not knowing Ed was standing right behind her.

“The blade cut into his face and it was just a few inches from his right eye. He could have been blinded… Beatrice was very upset.”

We’re glad Ed is ok – but as the old saying goes, ceremonial swords are all good and fun… until someone almost looses an eye.
