Poppy Delevingne threw the mother of all don't-you-know-who-I-am tantrums when she was refused entry to a VIP area at the British Fashion Awards in London last week… because the bouncers clearly didn't know who she was. 

The big sister to model/actress of the moment, Cara Delevingne was at St Martin’s Lane Hotel’s Asia de Cuba bar and a bouncer presumably said: "If your name’s not Cara Delevingne you’re not coming in."

The model was with actress Kate Bosworth at the time and and one point she was heard saying, "This is b******t and you’re going to lose your job tomorrow. Congratulations." Harsh Pop!

Kate was then seen urging her friend to "get the f**k out of here," and the pair left in a rather grumpy mood. Eek!

Lesson learned: Don't get on the wrong side of Poppy!
