A woman pleaded guilty in a San Diego courtroom on Monday to stalking singer-actress Jennifer Love Hewitt after saying she believed the "Party of Five" actress read her mind and planned to harm her, prosecutors tell Reuters.

Diana Napolis, of the San Diego suburb of La Mesa, pleaded guilty to felony stalking in exchange for the dismissal of five other charges. She faces up to three years in prison when she is sentenced next month.

Napolis, 47, was reportedly diagnosed as delusional but competent enough to stand trial after spending five months in a state psychiatric facility, prosecutors said.

Hewitt, 24, was reputedly first threatened by Napolis outside a San Diego radio station. The stalker then continued trying to contact the actress in Los Angeles and via e-mail between July 29 and Nov. 3 of last year, according to Deputy District Attorney Fiona Khalil.

"She believed that Ms. Love Hewitt was part of a group that targeted her with so-called psychotronic technology," Khalil said. "Due to this technology (Napolis believed) they were able to tell what she was thinking."

There has been no comment from Hewitt or her representatives regarding the matter.
