Kelly Paniagua is an Australian actress, app creator, and author, best known as the wife of late Australian-American actor Julian McMahon. Born on December 15, 1977, in Australia, Kelly gained prominence after marrying Julian in June 2014 at Lake Tahoe, following a proposal in November 2013[2][5]. Julian, the son of the 20th Prime Minister of Australia, Sir William McMahon, was a renowned actor known for roles in "Profiler," "Fantastic Four," and "Nip/Tuck"[2][3]. Kelly is credited with creating an app and writing a children's book titled "Bedtime for Sarah Sullivan," which was inspired by Julian's relationship with his daughter, Madison[2][3]. Although she has been involved in various projects, much of her fame comes from her association with Julian McMahon. Over the years, Kelly and Julian attended several red carpet events together, maintaining a relatively private life despite their public appearances[3][5]. In recent years, Kelly has been in the spotlight due to her husband's health issues and subsequent passing. Julian McMahon died on July 2, 2025, after a private battle with head and neck metastatic cancer[5]. Kelly announced his death and shared a heartfelt statement, reflecting on his love for life and his family[5]. This event has brought Kelly into the public eye once again, as she navigates the aftermath of Julian's death while continuing to support his legacy. Currently, Kelly's own career and personal life are not as widely publicized as her relationship with Julian McMahon. However, her contributions as an author and her involvement in the entertainment industry remain notable aspects of her life and career.
