Emma Watson returns to her usual low-key style after playing glamour girl on the set of The Bling Ring

After spending years of her life playing bookworm good girl Hermione Granger, Emma Watson stunned fans with her sudden transformation on the set of her latest film last month.

The actress was spotted on a number of occasions on the set of The Bling Ring in tiny denim hotpants, killer heels and with long brunette hair.

But Emma, 22, looked back to her old self as she ran errands in North London today.

The pretty actress went low-key and comfortable - a far cry from her sexy character Nicki - in jeans, flat boots and a knitted cardigan.

The always-stylish star wore a Peter Pan-collar grey and white top and completed the look with warm scarf.

Emma is back on home turf after spending weeks on the set of The Bling Ring in Los Angeles.

Emma Watson prefers natural look

London: `Harry Potter` beauty Emma Watson says she prefers the natural look and and hates piling on cosmetics.

The 21-year-old actress feels biggest beauty faux-pas is wearing too much make-up as she thinks beauty comes from within, a website reported.

"The funny thing about me is that I do have a lot of products - I`ve always loved make-up and its ability to transform you. But I don`t actually wear a lot of it, so there is an irony that I own so much of it but wear so little. But I do love beauty products.

"But wearing too much make-up has been my biggest beauty faux-pas. I truly, truly believe that beauty is something that comes from within. You can only really look beautiful if you feel beautiful on the inside. It shows through your face, the way you move and the way you hold yourself," she said. 

Kristen Stewart: My style is messy

Kristen Stewart's says her style is "all over the place."

The American actress was present at yesterday's Mulberry show at London Fashion Week, and sat in the front row poised next to British fashion royalty Kate Moss.

Kristen was impressed with what she saw on the catwalk, but says her own fashion choices sometimes leave a little to be desired.

"All over the place right now," she told vogue.co.uk, when asked to describe her personal style.

"I have different versions of myself and a standard uniform - I wear jeans. It's cool to have another side of things. I have phases."

Kristen admitted Fashion Week isn't usually her scene. However, the 21-year-old insisted she is interested in style and its importance in the celebrity world.

"Actors and actresses have a hand in both worlds [acting and fashion]. You have to stay involved in it to be interested," she explained.

Kristen likes her simple style. The star takes great pleasure in choosing her own garb, rather than leaving it down to a stylist all the time.

"I love what I wear, I mean I love choosing what I wear," she said.

Kristen is enjoying her time in London at the moment. The brunette beauty loves admiring the eclectic fashion in the British capital and appreciates her anonymity.

"The people are really great. I like walking around here, I don't really get bothered by anyone," she said.
