LOS ANGELES (AP) -- The alleged ringleader of a series of burglaries at the homes of celebrities has pleaded no contest to stealing from Lindsay Lohan and reality star Audrina Patridge.

Nicholas Prugo entered the plea Friday in Los Angeles and is expected to serve two years in state prison.

Neither Lohan or Patridge, a star of "The Hills" series, attended the hearing.

The plea came in exchange for Prugo testifying against three other people suspected of helping him break into the homes of stars.

Prugo will be sentenced May 4, or after the cases against the remaining defendants have concluded.

The 21-year-old had also been charged with conspiracy and burglarizing the homes of Orlando Bloom, Paris Hilton and Rachel Bilson, but those counts were dropped in exchange for his plea.
