The Goldbergs and Schooled alum has filed suit against Gabriel Tigerman, the husband of Kathryn Fiore Tigerman, alleging that "Gabriel's been on the warpath to destroy his career through threats, harassment and intimidation of anyone who dares to hire him," reports TMZ. In an interview with the Los Angeles Times in July, Kathryn Fiore Tigerman, a MADtv alum, accused Callen of raping her in 1999. Callen has denied her allegation. TMZ adds that Gabriel Tigerman allegedly contacted Callen's reps at CAA and has reached out to comedy clubs, urging them not to book him. Meanwhile, the sexual misconduct allegations haven't stopped comedy clubs from booking Callen.
