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.

It is the real-life story of a gang of teens who robbed the homes of a host of celebrities including Paris Hilton, Orlando Bloom, Megan Fox, Rachel Bilson, Ashley Tisdale and Lindsay Lohan.

Emma stars alongside Kirsten! Dunst, Leslie Mann and Gavin Rossdale.

Her character prefers a far flashier look than Emma, with costumes including stiletto heels, pink velour tracksuits and midriff tops.

Emma gave fans an insight into her onscreen preferences, tweeting: 'Nicki likes Lip Gloss, Purses, Yoga, Pole Dancing, Uggs, Louboutins, Juice Cleanses, Iced coffee and Tattoos.'

The film, directed by Sofia Coppola, is due for release next year.

She is also filming comedy The End Of The World alongside Seth Rogan, Jonah Hill, James Franco and a host of other big names. The film is a parody which sees the stars play themselves and facing The Apocalypse while attending a party at James Franco's house.
