The outpouring of love and support for Shannen Doherty during her battle with breast cancer grows bigger and more inspiring by the day. On Monday actress Sarah Michelle Gellar joined in, dedicating her #MondayMuse Instagram post to her "brave friend."

"My #mondaymuse (and really everyday #muse) is my brave friend @theshando," Gellar wrote alongside a recent photo of the two of them (above). Doherty, who shared the experience of shaving off her hair last month, wears a patterned pink scarf tied around her head.

"I've always said she is one of the most loyal friends I've ever known, and now while she is facing the toughest journey of her life, she is sharing it with friends she has never met in the hopes of helping other people who are going through the same struggle," Gellar went on to write. "That's a true friend."

After revealing her diagnosis in August 2015, Doherty, 45, has been very open about her battle with cancer. On top of taking her Instagram followers through the emotional process of shaving her head, the Beverly Hills, 90210 star most recently opened up about how her support system has helped her through this impossibly tough time.
