Simmons was originally sued in December for allegedly groping the plaintiff and making "unwanted, unwarranted sexual advances" during a Nov. 1 interview with Simmons and his Kiss bandmate Paul Stanley at their Rock & Brews restaurant at San Manuel Casino in Highland, California.
According to the lawsuit, Simmons repeatedly grabbed the plaintiff's hand and "forcefully placed it on his knee and held it on his knee." It also alleged the rocker "forcibly flicked/struck" the plaintiff's throat, later providing an "incoherent explanation" for his behavior.
The suit also said that while posing for a promotional photograph together after the interview, Simmons "reached toward Plaintiff Doe's buttocks and touched it."
The plaintiff was identified in the documents as a "long-time on-air personality for a local rock station."
"Defendant Simmons turned standard interview questions into sexual innuendos, which made plaintiff Doe extremely uncomfortable," the suit read.
Her attorney, Willie W. Williams, told The San Bernardino Sun in an interview last year her client was "embarrassed and humiliated by the incident with Mr. Simmons" and "filed suit because she wanted to make a strong statement that this behavior is unacceptable and she wants to see an end to this type of behavior."
