On and off screen, Emma Watson is known for being a good girl.

So it was quite a surprise to see the actress hanging around outside infamous Lynwood jail in Los Angeles yesterday.

However, fans needn't worry, the Harry Potter star was simply filming her new movie The Bling Ring.

With brunette hair extensions and a short black skirt, the 21-year-old was filming scenes as her character Nicki checks into jail - where Lindsay Lohan, Paris Hilton and Nicole Richie also served time - after being found guilty of burgling celebrities' houses.

The Bling Ring is based on the real-life story of a gang of teenagers who robbed stars including Hilton, Orlando Bloom, Megan Fox, Rachel Bilson, Ashley Tisdale and Lohan between October 2008 to about August 2009.

Ironically Lohan was also an inmate at Lynwood two years ago at the same time as Alexis Neiers - one of the convicted gang members.

And it appears filming is going well as Watson wrote on Twitter last week: 'Filming Bling Ring is going great. As Israel would say 'we are slaying this!'. Thanks for the good luck messages.'

The day before, Watson was spotted with a friend running for a cab on Robertson Boulevard wearing a pair of very short shorts.
