Courtney Leigh Ames was one of six people charged with snatching more than $3 million (GBP1.9 million) worth of goods from properties belonging to stars including Hilton, Lindsay Lohan and Orlando Bloom between 2008 and 2009.
And on Friday (14Dec12) she pleaded no contest to one count of accepting stolen property from the socialite in exchange for prosecutors dropping three other charges, including felony residential burglary.
Ames, who is due to be formally sentenced on 1 February (13), is expected to be ordered to stay out of trouble until 2016 and complete 60 days of community service.
Hilton declined to seek damages, reports the Associated Press.
The case has captured the attention of the media, with director Sofia Coppola even turning the thieving scandal into a new film. The Bling Ring, starring Emma Watson and Leslie Mann, is due out next year (13).
