Cara Delevingne and her girlfriend St Vincent have split after dating for a year-and-a-half. The model/actress and the musician decided to part ways after their long distance relationship became "too much" to bear.

The split comes just a month after the Suicide Squad star declared that she was madly in love with the musician.

According to The Sun, the pair decided to split as their long-distance relationship became "too much" to handle.

"Cara and Annie [St Vincent] still care about each other, but pressures of the long-distance romance just became too much. The cracks were beginning to show on Cara's birthday in August when Annie wasn't there for her party," a source was quoted as saying.

"Instead she posted a very flat birthday message on Instagram. They decided to call it a day but remain pals and are hoping they can work things out as its no doubt they really love each other. But at the moment Cara has been trying to distract herself by partying," the source added.

Earlier, Cara was spotted partying at the Burning Man festival in Nevada's Black Rock Desert.

"Before, I didn't know what love was - real love. 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 24-year-old said of St Vincent in the September issue of Vogue.
