Lifestyle diva Martha Stewart will be under home confinement for three extra weeks beyond her original five-month sentence, her lawyer said on Wednesday. BEIJING, Aug. 4-- Lifestyle diva Martha Stewart will be under home confinement for three extra weeks beyond her original five-month sentence, her lawyer said on Wednesday.

"Martha Stewart has agreed to an extension of the terms of her home confinement until Aug. 31.," her lawyer, Walter Dellinger, said in a statement released Wednesday.

He did not elaborate on why the house arrest had been extended.

The extension follows the New York Post reports over the weekend that Stewart, who was convicted of lying to investigators about a suspicious stock trade, violated terms of her home confinement by going to a yoga class and motoring around her estate in an off-road vehicle.

She is only permitted out of her home for 48 hours a week to work and for religious services, food shopping and doctor's appointments. Stewart also must wear an electronic monitoring bracelet around her ankle.

Stewart, who turned 64 on Wednesday, served five months in a West Virginia prison camp and was scheduled to complete five months of house arrest on Aug. 10.
