In a touching tribute on Instagram, Holly Marie Combs, co-star of the hit show "Charmed," honored her long-time friend and colleague, Shannen Doherty, who sadly passed away at the age of 53 on Saturday, July 13. Doherty had been battling cancer for several years.

Combs shared a series of photos on her Instagram post, alongside a heartfelt caption that expressed her deep loss. She referred to Doherty as her "better half of 31 years" and mentioned feeling a hollow in her chest and struggling to catch her breath. Combs also recognized that a part of her was missing, even though she could imagine what Doherty would say to her at this moment.

Addressing Doherty directly, Combs acknowledged her undying spirit, which she believes will live on not only in her, but also in Combs' children, whom Doherty loved as her own. She expressed her conviction that they would embody Doherty's sense of purpose, pride, truthfulness, and a determination to stand up for what is right. Combs praised Doherty's legacy, stating that her fire would continue to burn in the many other "Charmed" cast members whom she had influenced and nurtured. She described Doherty as a fierce fighter and her most ardent champion, her loyal protector, and her best friend who taught her the true meaning of family.

In addition to Combs' tribute, Rose McGowan, who replaced Doherty on "Charmed," shared her own emotional message on Instagram. McGowan described Doherty's passion for her craft as often being mislabeled as trouble, but she insisted that Doherty was a true inspiration. McGowan praised Doherty's work ethic and her lifelong dedication to her craft. She honored Doherty as a "force of energy" that would live on indefinitely, urging her to rest as a warrior.

The passing of Doherty deeply affected other members of the Hollywood community as well. Doherty's former "Beverly Hills, 90210" co-stars, Jennie Garth, Tori Spelling, Jason Priestly, Carol Potter, and Gabrielle Carteris, expressed their shock and sadness, sharing their condolences and memories of their time together.
