UPDATE: Lawless was sentenced to 120 hours of community service and ordered to pay $547 to a port company. The judge refused to order the actress and her fellow protesters to pay reparations to Shell Todd Oil Services.
Lucy Lawless is copping to some lawlessness of her own.
The Spartacus star has pleaded guilty to trespassing an oil-drilling ship in New Zealand in February as part of a concerted environmental protest against global warming, according to published reports.
Lawless, who faces up to three years in jail, was arrested on Feb. 27 after she and six other Greenpeace activists boarded an oil-drilling ship docked at a New Zealand port, climbed atop its tower and hunkered down for four days.
The ship was set to sail for the Arctic, and the group sought to raise awareness of the impact that Arctic oil drilling had on global warming. Lawless, 44, was photographed waving a sign that read, "STOP SHELL," the company behind the operation.
The native New Zealander was initially charged with burglary, but that charge has reportedly been reduced. She's due to be sentenced in September.
