Chapman, 28, is the daughter of a Russian diplomat. Photos of the redhead that showcased her social life and travels were splashed all over the tabloids, and she was branded a femme fatale.

Prosecutors say Chapman used a specially configured laptop computer to transmit messages to another computer of an unnamed Russian official.
She was arrested at a New York Police Department precinct after turning in a fake passport an undercover FBI agent had given to her. She pleaded guilty to conspiring to act as an unregistered agent of a foreign country.
