The 31-year-old actress was among a number of stars, including Paris Hilton, Lindsay Lohan and Orlando Bloom, whose homes were targeted by a gang of young thieves between 2008 and 2009.
The case of the celebrity burglar bunch inspired Coppola's new film "The Bling Ring", starring Emma Watson and featuring victim Hilton in a cameo role, reported Daily Star.
However, Bilson, who reportedly lost her mother's engagement ring in the break-in, insists she doesn't agree with the decision to make the movie.
Bilson testified during the trial of real life gang members and revealed the burglary left her so scared, she couldn't sleep in her bedroom for weeks afterwards.
"It took me a while to feel comfortable staying there. I wouldn't sleep in my bedroom for about a month. And I was convinced that I needed to sell my house and get out of there, because I was very scared. But I'm still there," she added.
