Kristen Stewart prefers looking natural.
The 'Twilight' actress has been made the face of fashion house Balenciaga's new perfume Rosabotanica and sports an exotic flower sash and smoky eye make-up in the adverts, but claims she prefers a more natural look when she's off duty.
She said: "I never wear a lot of make-up. That was never someting I liked. But black eyeliner is always in my bag. I like the messy look. I always wash my face before I go to bed, but I never clean around my eyes and that looks great in the morning."
Fashion designer and creative director of Louis Vuitton, Nicolas Ghesquière, has also chosen the 23-year-old star for his new campaign and she admits she likes to inspire fashion.
She told German VOGUE: "I like to be a muse. You meet so many talented people who inspire me. I like the creative energy at photo shoots."
Kristen - who will next appear on screens in 'Camp X-Ray' as a guard at Guantanamo Bay - also revealed that she only achieves her stunning red carpet looks with the help of stylists.
She said: "I really like getting dressed up for photoshoots or movie premieres. And I like bold eye make-up - if it suits the event. But to be honest, everything you see on the red carpet is down to the hard work of stylists. In my private life I prefer a natural look."
