Suspected Burglar Bunch thief Nick Prugo has pleaded no contest to jacking expensive stuff from the homes of Lindsay Lohan and Audrina Patridge ... and told prosecutors he's totally willing to throw his fellow suspects under the bus.
21-year-old Prugo cut a plea deal ... in which he's expected to serve 2 years in state prison for the Hollywood Hills crime spree.
In exchange for the plea, prosecutors agreed to drop other charges related to burglaries at the homes of Orlando Bloom, Paris Hilton and Rachel Bilson.
Prugo also agreed to testify against three other people who allegedly participated in the crime spree.
Prugo is due back in court on May 4 to make it official.
