KEY POINTS:
Paris Hilton could serve just half of her jail sentence due to prison overcrowding, police authorities have said.
The hotel heiress – who was last week jailed for 45 days for driving with a suspended licence – could serve less than three weeks due to a state directive to reduce terms for good behaviour and to ease overcrowding.
Los Angeles County sheriff's spokesman Steve Whitmore said: "It's possible that it could be 21 days to 23 days. It's a complicated formula that the state sets down. It's possible she could do less time.
"Our jail is bursting at the seams and some women inmates have been released after serving only 10 per cent of their sentence."
Last year, Lost actress Michelle Rodriguez was released within hours due to overcrowding, despite being sentenced to 60 days in jail for violating probation after her drunk driving arrest in Hawaii.
Paris will be eligible for 'Good Time/Work Time' credit, a federal mandate which allows inmates sentenced to 11 days or more to leave early if they behave themselves.
Every four days that an inmate spends behind bars "in an acceptable manner" count as six days.
Meanwhile a 'Save Paris' rally held in New York's Greenwich Village flopped when only three protesters turned up.
The trio held up posters of 'The Simple Life' star with the words "martyr" and "victim" on them.
