She was scouted outside Harrods
Anya landed her first modelling contract when she was spotted outside the luxury department store by Sarah Doukas who signed Kate Moss and Cara Delevingne to Storm Management.
The actress initially thought she was being stalked when a car started to curb crawl her.
She said: "I thought 'Oh no, this is the end, So I picked up my dog and started to run."
