"Anna said when those photos were taken she was 21 years old. He asked her to pose and she agreed because she thought they would be private," ABC News quoted her attorney, Robert Baum, as saying.
Baum also said Alex Chapman had told lies about his 28-year-old client in interviews with the newspapers, including that her father was a Russian KGB agent, ABC reported Wednesday.
"Virtually all the statements he made about her are not true," Baum said, adding her father, Vasily Kushchenko, is an embassy official for Russia.
"He spent many years in Kenya and Zimbabwe -- not exactly where you would send your KGB agent to."
Baum said while the Chapmans' divorce had not been amicable, Anna Chapman was "disappointed" by what she regards as her ex-husband's betrayal.
She was among several alleged secret agents arrested by federal authorities last month and is being held without bail in New York.
