Cara then screeched at the door staff because she couldn't believe they had no idea who she and Amber, 30, were.
Mr. Langer explained: "Cara kept telling the staff, 'Don't you know who I am? I'm Cara Delevingne. I'm Cara and this is my friend Amber who's just got divorced!'
"She kept on telling our staff how famous they were but I'm afraid we are quite used to that. Then she said: 'Let us in. We just want to see some girls dancing and have some fun!' "
Cara and Amber arrived at the saucy venue with Margot Robbie and 12 other friends but things turned nasty before they even arrived as staff told them they could only secure a table if they bought a bottle of champagne - the rules that apply to all customers that want the added extra at the club.
Mr Langer said: "Cara wasn't having any of it and kept turning round to the other girls in amazement.
"She was getting quite angry and agitated but there was nothing we could do about it.
"In the end we told them all to go away because they didn't want to pay and she swore and threw her hands up."
