The 35-year-old star is close friends with Olivier Rousteing and the Balmain designer admires the global reach she has built up.

Olivier said: ""I don't care what anybody says about Kim. I love her. I love that she is a woman but has more power than so many men. And I love that she is so powerful but always takes care of the people she loves. And I admire her, because she is the best in the world at communicating with people."

As well as Kim and her husband Kanye West, Olivier is also close friends with the likes of Rihanna and Justin Bieber, but insists their bonds are genuine and run far deeper than showbiz friendships and promotional opportunities.

He told the Guardian newspaper: "When I post on Instagram about Justin or Lewis [Hamilton] or Kim or Rihanna, that's a real friendship I am showing. If I love your album, I'll post about your music. But also, we can call each other at 5am when we just need to talk."

And the designer insists whenever celebrities are pictured in his creations - such as a blue fringed and latticed leather coatdress Rihanna has been seen in - it is because they have a genuine relationship, rather than him relying on people wearing his garments in order to promote Balmain.

Explaining how the 'Work' singer acquired the coatdress, he said: "The night of the [menswear and some resortwear] show, [Rihanna] texted me and she was like, 'Babe, I love that show, so beautiful, it was amazing.' So I texted back, 'What do you like?' and she sent me a picture of the blue coat and I was like, 'OK, I'll send it tomorrow.' There is no strategy. It comes from a text, from love and friendship. I don't need PRs.

"I mean, of course I need PR. But I don't need them for that.

"When you see someone wearing Balmain, there's no contract. It's a real relationship, and that's the magic."
