Los Angeles, May 17 (IANS): Actress Emma Watson says she watched “Keeping Up with The Kardashians” and "The Hills" to prepare herself for “The Bling Ring”.

The 23-year-old, who plays Nicki in the film, watched the reality shows to understand the psychology of her character, reports femalefirst.co.uk.

“I watched a lot of 'Keeping Up with the Kardashians' and 'The Hills', and I tried to understand the psychology of this kind of girl as much as possible. I didn't want her to be just a parody. The accent was hard as it was a particular kind of dialect. I also thought a lot about what her parents must have been like,” she said at the Cannes Film Festival.

“The Bling Ring” is a film based on a group of fame-obsessed teenagers who use internet to track celebrities' whereabouts in order to rob their homes including Lindsay Lohan, Paris Hilton and Orlando Bloom, but Watson insists the film is not just another heist movie.

She explained: “This really isn't a heist movie. It was about how these kids wanted to pretend for just two hours or so that they were actually Paris Hilton and living that life.”
