The 49-year-old "Blue Lagoon" star turned to cops last month, claiming John Rinaldi had left her strange notes, scared her children and posted nasty comments about her co-workers on social media, according to the New York Post.
However, Rinaldi is claiming he simply contacted the actress about donating to his foundation, The Sandy Hook Kids Center.
"I've done nothing wrong. I left her a very polite, professional letter. I have really respected her space. I've never once interjected in her personal life," he said.
Rinaldi is reportedly wanted on fourth degree stalking charges.
Shields has declined to comment.
