Cara Delevingne ''lives on'' vegan chocolate.

The 22-year-old supermodel reportedly can't get enough of the snack and even carries it around in little pouches in her pockets so she can get her fix at a moment's notice.

The slender beauty is also said to give out little cubes of the vegan treat at top catwalk shows to shock the other models who live off a diet of ''water and cigarettes''.

A source said: ''Cara lives on vegan chocolate and carries it around in little pouches in her pockets.

''She loves to hand out vegan chocolate pieces at shows and shock the skinny models living on water and cigarettes. She's the most anarchic, different, original model I've ever come across.''

And the Burberry model made sure vegan chocolate was on the menu during a recent tea party which she held for her pals in New York City.

An insider told the Daily Star newspaper: ''A few of us went to have an afternoon's fun with Cara in New York. We were stunned that a slim model entertains with chocolate and tea.

''As soon as we arrived her help brought in a silver tray of vegan chocolate pieces and poured us this Russian caravan tea.''
