A random prince gave Kendall Jenner this insanely generous birthday present

And she was so drunk she forgot she'd been given it (we've all been there)

Remember that time on your 21st birthday when a prince turned up and gave you a Rolls Royce, but you were so drunk that when you woke up the following day you had completely forgotten it ever happened?

No?

In the world of the Kardashian family it would seem this sort of thing can and does happen. During an appearance on Jimmy Kimmel, Kendall's half sister Khloe recalled an incident which occurred on Wednesday night when the family were celebrating Kendall Jenner's 21st birthday at Catch restaurant in Los Angeles.

'We go outside and there's a guy with a Rolls Royce' she told Kimmel, 'we're like "what's the gift, the guy or the Rolls?"'

It was the Rolls.

'And then the guy just hands her the keys to this car' Khloe continued, 'we don't know who this guy is, he's some prince.'

'I was like "is this a joke?" I think on my 21st birthday I got like a dinner and a purse or something.'

Khloe was even more disbelieving the following day, when her sister was unable to recall the gift. '"Oh my God I forgot I got a car!" That's how drunk she was,' she said of her sister.

We can't imagine getting drunk enough to forget we'd been given a £100 000 car. But maybe the drinks were just really, really strong. Or Kendall's just not that into cars.

Whoever you are, Anonymous Rich Prince, this writer's birthday is on 7th February and she will be celebrating with friends at Numero Uno restaurant in Battersea if you'd like to hover outside with a Rolls Royce.
