New York ? Home decorating diva Martha Stewart will not take the stand in her own defense at her stock-fraud trial, her lawyer said Tuesday.

Attorney Robert Morvillo said Stewart’s defense team would call just one witness — a former lawyer who attended an interview she gave to investigators in 2002. That witness is expected to testify this morning.

Lawyers for Stewart’s co-defendant, former stockbroker Peter Bacanovic, presented their last witness Tuesday and will rest their case today.

Bacanovic spokesman Lou Colasuonno said Tuesday that the broker’s defense team believed “the government hasn’t made its case.”

Earlier Tuesday, prosecutors aggressively attacked the credibility of a business manager for Stewart, who helped the defense on Monday when she said Stewart’s broker had mentioned a desire to unload Stewart’s ImClone shares at $60 or $61.

Heidi DeLuca placed the conversation on Nov. 8, 2001, about seven weeks before Stewart sold 3,928 shares of ImClone Systems stock.

Stewart and Bacanovic are accused of repeatedly lying to investigators about the circumstances of the ImClone sale.

DeLuca, who handles finances for Martha Stewart Living Omnimedia and for Stewart, also said Stewart billed her company for a vacation she took just after selling her ImClone stock. DeLuca testified she was instructed to submit the vacation for reimbursement as a business expense.
