She’s used to wearing cloaks and gowns from her role as Hermione in the Harry Potter films.

But on Sunday, Emma Watson decided to ignore the sunny temperatures and to wrap up in a coat that hid her petite frame.

The 23-year-old was joined by a friend as they took a stroll through West London.

Nice day for a stroll: Emma was spotted out in West London

She paired the jacket with a white button-down t-shirt, dark jeans and heeled Chelsea boots.

However, although she’s out of Hollywood, the Perks of Being a Wallflower actress added the Hollywood A-lister favourite – a pair of dark sunglasses.

With minimal accessories, and messy hair, it was a far cry from her usual red carpet attire.

Emma looked content as she and her friend walked the streets of London.

The My Week With Marilyn actress is currently dating student Will Adamowicz, who was nowhere to be seen on her West London excursion.

The star’s latest film, The Bling Ring, is due out in UK cinemas on 5 July.

In it she plays Nicki, a member of a group of fame-obsessed girls who track where their favourite celebrities are in order to rob their homes.

Her character is a bit of a wild card who enjoys the buzz of stealing, along with living an A-list lifestyle – something that Emma has found abhorrent.

Emma has described the character as ‘superficial, materialistic, vain, amoral’ and added: ‘She’s all of these things and I realised that I hated her.’
