Have 'completely in love' Cara Delevingne and St Vincent split up?

Updated: 

Model and actress Cara Delevingne has reportedly split from her girlfriend St Vincent - despite recently gushing that she was "completely in love".

Cara told British Vogue for its September issue that she had discovered the meaning of "real love" after falling for girlfriend Annie Clark, otherwise known as singer-songwriter St Vincent.

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

But the couple, who have kept their relationship very private and have been dating for a year and a half, have now apparently gone their separate ways.

The Sun reports that they split during Cara's hectic tour to promote her film Suicide Squad.

Cara herself has spent the last few weeks mainly off-grid at Burning Man festival in Nevada's Black Rock Desert, posting a picture on Instagram reading: "Excuse me while I disappear."

The relationship seems to have been strained by the pressure of a long-distance romance, with St Vincent apparently not making it to Cara's birthday in August.
