Singer Rita Ora says she is so close to her model friend Cara Delevingne that they call each other their wives. Ora, 22, met Delevingne through mutual friends and has no time for men now because she has her better half. “I have no time for the opposite sex at the moment. Strictly none. I’ve only got a wifey,” said Ora who dated Rob Kardashian last year. “She’s officially mine. She’s, like, untouchable. I’ve taken her off the market. We call each other ‘wifey’,” thesun.co.uk quoted Ora as saying. “You know what a wifey means? It’s like your other half. Like when you get married, like, that’s your wife,” she added.
