Joined by her castmates, Watson looked every inch the movie star as she filmed scenes in California.

One sHot sees the Harry Potter actor, who plays ringleader Nicki, sporting long brown locks and oversized sunglasses as she walks down the street with friends.

In another, she attends an all-female prison.

Since the Harry Potter franchise came to an end, we are more used to seeing Watson with a short pixie hair cut and boyish clothes, so this role will truly be a transformation for the 21-year-old.

Emma recently tweeted how well filming was going, saying: ‘Filming Bling Ring is going great. As Israel would say ‘we are slaying this!’. Thanks for the good luck messages.’

The Bling Ring, which is being written and directed by Lost In Translation’s Sofia Coppola, is based on the true story of five rich teenage girls who break into celebrities’ homes to steal jewellery.

The Bling Ring is a nickname given to the gang of girls involved.
