We’ve all done it.
You’re at a party, when you’re confronted by a very familiar face but you just can’t quite recall where you know it from.
So spare a thought for Australian actress Margot Robbie.

The ‘Wolf Of Wall Street’ star has opened up about the time she and some friends were joined by a familiar face inside a photobooth at a party thrown by the model Suki Waterhouse.
Despite there being plenty of recognisable people at the housewarming bash in London, poor old Margot failed to clock that the very famous photobomber was in fact... Prince Harry.

Like we said - we’ve all done it.
And her excuse?
“He wasn’t wearing his crown,” she told US chat show host Jimmy Fallon.

And it gets even better - Margot mistook Hazza for another famous redhead - Ed Sheeran.
And that didn’t go down too well with the Prince, either.
“He got really offended,” Margot added.
Off with her head!
