Teresa Yuan pleaded guilty Friday in Brooklyn federal court. Prosecutors say she sent 504 emails and 120 webcam videos of herself to a Cotillard fan website over four days in 2011.
In some of the videos shown in court, Yuan appears to be topless, hisses like a cat and discusses playing Russian roulette. Her lawyer says he agrees the videos could seem threatening.
The Daily News reports the 32-year-old Queens resident told a judge that she's undergoing psychiatric treatment for bipolar disorder.
The charge carries a sentence of up to 16 months in prison, but her lawyer says prosecutors have indicated they wouldn't object to probation and psychological treatment.
