Paris Hilton's jail sentence for a probation violation has been reduced.

An LA County sheriff's spokesperson says it was shortened from 45 days to about 23 days due to "good behavior." 

Apparently, several factors were considered in reducing her stay in jail, including the fact she appeared at her latest court date.

The spokesperson says Hilton will spend her time in a cell separated from the general inmate population.  

Hilton must report to the Century Regional Detention center by June 5.
