Diana Bianchi, the young woman in the middle of the Christie Brinkley split scandal, will testify in divorce court. Her attorney, Rosemarie Arnold,  tells ET today: "She is looking to move forward in her life and regain her anonymity. She has not pursued a career in music by her own choice. That choice has nothing to do with Christie Brinkley or Peter Cook. She wants the media to respect her privacy."

Last year, the then 19-year-old New Yorker found herself in the middle of a media storm when it was revealed that she had had an alleged affair with Christie's husband, Peter Cook.

Now, her attorney says that she has been subpoenaed to testify in their divorce trial.

Just last week, it was determined that the trial will be open to the public.

"We are pleased with the judge's decision and wish this didn't happen," Christie's lawyer told ET. "Since the case hasn't been able to be resolved, Ms. Brinkley looks forward to her day in court."

The trial is set to begin on July 2.
