"I'm completely in love," she said. "Before, I didn't know what love was - real love."

Cara and American singer-songwriter St Vincent have kept details of their relationship private, but now Cara has revealed: "I didn't understand the depth of it. I always used to think it was you against the world.

"Now I know the meaning of life is love. Whether that's for yourself or for the world or your partner."

The 23-year-old, who was photographed by Mario Testino for the cover, said she did not care if people called her gay but said her sexuality was "liquid".

She explained: "As a child, I used gay as a bad word, as in, 'That's so gay.' All my friends did... I'm obviously in love, so if people want to say I'm gay, that's great.

"But we're all liquid - we change, we grow."
