She caused a stir after she chopped off her locks for a dramatic pixie cut as soon as filming on the Harry Potter movies wrapped.

But now Emma Watson has set about changing her image once more.

The actress has undergone another transformation, debuting a new set of hair extensions as she set about filming her new movie earlier today.

New hair do: Emma Watson has transformed her locks, debuted her new hair extensions on the set of Sofia Coppola’s The Bling Ring earlier today

Comfy look: Filming on the true-life movie about a group of teenagers who raided celebrities’ homes started this week in Los Angeles,

It was only yesterday that she was seen jetting in to Los Angeles fresh from a weekend in Boston.

And as she was spotted walking through LAX, Emma still had her cropped hair, albeit growing out and clipped up to stop stray hairs falling into her face.

But now she’s filming Sofia Coppola’s new film The Bling Ring, the 21-year-old has adopted yet another new look. 

Taking a break: Emma shows off a bit of skin in between takes

She was seen on set with her brunette hair flowing with a poker straight ‘do to below her shoulders. But while her transformation was a fairly drastic one compared to the shorter styles we’ve become accustomed to seeing her in in recent times, Emma had yet to unveil her movie wardrobe.

The star stepped out in unflattering red jogging bottoms, covered up by a large bathrobe.

Out to it: Emma falls fast asleep on the sun lounger

And despite the sunny weather in LA, Emma also wore a large padded jacket over the top of the green gown.

Comfort was also key as she strutted out in beige UGG boots.

The actress, who played Hermione Granger in the wizard franchise throughout her childhood and beyond, is continuing to move away from the films.

She is now concentrating on working on the film, which only began shooting this week, about a group of celebrity obsessed teenagers who raid a string of stars’ homes.
