Gemma Arterton believes she has her own guardian angel.

The 26-year-old actress' mother Sally-Anne told her when she was a child that if you see a white feather it means there is an angel on your shoulder helping you, and Gemma is convinced her late grandmother is protecting her in her life.

In an interview with Vogue magazine, she said: "My mum is very psychic and believes in angels. I suppose it sounds quite twee when you describe it that way ... I have these feathers that follow me everywhere. My mum told me that whenever there's a white feather, it's your guardian angel. I think my guardian angel is my nan. When I arrived in Germany (to film 'Hansel and Gretel'), I opened my suitcase and there was this big white feather on top. And I thought, 'How did that get there?' This happens a lot."

Gemma's belief that she has her own protector influences her career and she has made decisions about her work based on the appearance of the mysterious feathers

Recalling a time when she discovered a white feather in her pocket when she was auditioning for a role she wasn't convinced was right for her, she said: "I decided not to do the movie. It just wasn't right. It's weird isn't it?"
