Lindsay Lohan is believed to have completed her court-ordered community service.

The troubled actress - who was working at the Los Angeles County Morgue as part of her sentence for breaking her probation in relation to a 2007 DUI (driving under the influence) case - is also said to have finished the mandated psychotherapy requirements ahead of schedule.

A source told 'Access Hollywood': "Lindsay has already completed her community service and therapy requirements."

In addition to serving four-and-a-half hours of a 30-day sentence at the Century Regional Detention Facility in Lynwood, California, last month, the 25-year-old star was ordered by Superior Court judge Stephanie Sautner to undergo psychotherapy sessions and serve 423 hours at the county morgue by March 29, 2012.

A representative for Lindsay added: "We never comment on Lindsay's community service progress. Suffice it to say she is being diligent and complying with all court-mandated requirements."

The star was recently hailed as "polite and hard-working" by law-enforcement officials at the Los Angeles County Morgue, who claimed Lindsay was keen to finish the required hours and then get a head start on the duties she needs to complete before her second status hearing.

They said Lindsay had earned a "good reputation" at the morgue as she is "polite, hard-working and never complains".
