The actress was spotted fooling around in the Los Angeles heat as she enjoyed some down time with her crew and some cast members.

The Harry Potter star was clearly in a playful mood as she hid behind a car and pretended to hold up her fingers like a gun.

Emma, 21, then ran out from behind the vehicle as she pretended to chase someone.

She looked animated as she ran along wearing a large black coat.

The actress was later spotted as she laughed and chatted to co-workers in a baggy jumper emblazoned with white stars.

And despite the LA heat she warmed up with a scarf wrapped around her neck.

She has spent the last week in the sunny city filming for Sofia Coppola’s new film about a group of Hollywood teenagers who target celebrities’ homes.

Emma debuted a new look for the role, as she showed off longer locks after getting extension last weeks.

And she modelled the new look again as she fooled about on Tuesday, when she was also joined by rocker Gavin Rossdale, who appeared on set.

He wore a pair of dark jeans and trainers with a black jumper, while he wore his hair in a ponytail as she strutted around.

They join Kirsten Dunst in the film, who showed off a more grown up look during filming on Monday.

She was spotted on set of the movie yesterday sporting a large grin as she got to work wearing a smart yet sexy outfit.

She sported a black jacket over a collared peach blouse and also wore a black pencil skirt that fell mid-thigh showed off a lot of leg.

Kirsten further accentuated how slim her bare pins were with a pair of black and white printed court shoes.

The blonde wore natural looking make-up and was holding a black crocodile leather clutch bag.

The Sofia Coppola project has only just commenced filming and is set for release next year.

The movie is based on a true story which saw stars including Paris Hilton, Orlando Bloom, Megan Fox and Lindsay Lohan all targeted by the gang, which was made up of six members.

It is the second time the story will be portrayed on film, as a Lifetime movie starring Austin Butler and Jennifer Grey was shown on television last year.
