The woman who claims Alabama Senate hopeful Roy Moore attempted to sexually assault her when she was a 16-year-old schoolgirl – and offered her signed yearbook as proof they knew each other – emerged Friday to change her story.

Beverly Young Nelson now says that under what she says is Moore’s signature are some notes, including a date and location that she herself wrote, not Moore.

In an interview Friday with ABC's "Good Morning America," Nelson revealed she scribbled "12-22-77" "Olde Hickory House," where she worked as a waitress, to commemorate the signing, which reads: "To a sweeter, more beautiful girl I could not say Merry Christmas. Christmas 1977. Love, Roy Moore, D.A."

But at a press conference last month, Nelson said Moore, who is running for U.S. Senate on the GOP ticket, signed the yearbook and mentioned nothing about the notes she had added in her own writing. Moore has stated he does not know Nelson and disputes the authenticity of the handwriting.

Nelson’s attorney Gloria Allred said her client will hold a press conference Friday afternoon to deliver expert evidence that Moore, who was in his 30s and a district attorney at the time, did sign the yearbook.

Nelson came forward last month with claims that Moore offered her a ride home after work, but instead parked the car and tried to assault her.

She told her story just days after The Washington Post reported the allegations of Leigh Corfman, who said she was 14 when Moore undressed her and touched her over her underwear.

"It sickens me to wonder what may go on with him if he gets into office," Nelson, a Republican and supporter of Donald Trump, told "Good Morning America."

"He could be doing this still. We don’t know. And, then again, I hope that he’s changed. I pray that he’s changed. I really do.”

A total of nine women have accused Roy Moore of sexual misconduct. He denies the allegations and says he does not know any of the women.

Moore has been in a neck-in-neck race with Democratic challenger Doug Jones. After initially distancing themselves from Moore, President Donald Trump and other Republicans have now endorsed him.

The special election in Alabama is Tuesday.
