Brian Austin Green is sharing an update on his friend and former Beverly Hills, 90210 co-star, Shannen Doherty, amid her ongoing cancer battle.
Green, who was revealed as the singer behind Crash Test Dummy on The Masked Singer Australia Monday, spoke to the Herald Sun after his un-masking, where he shared how Doherty is managing.
"She's an incredibly tough person," Green told the outlet. "If there's anyone who could put up a real fight to cancer -- she's one of them."
In June, Doherty, 52, shared the devastating news that her stage 4 cancer had metastasized to her brain, with the TV star undergoing surgery to remove a tumor in her head.

View Story"The fear was overwhelming to me. Scared of all possible bad outcomes, worried about leaving my mom and how that would impact her. Worried that I would come out of surgery not me anymore," Doherty wrote at the time.
"It's not an easy situation, obviously," He continued. "But I love her to death."
In March 2015, Doherty, 52, was diagnosed with breast cancer, and after years of treatment, she entered remission. However, in February 2020, she announced on "GMA" that her cancer had returned and it was stage 4.
Doherty has been open about her experiences with cancer treatment and how it can affect her life. In 2021, she told "Good Morning America" that she did "not want to operate [like I'm dying]."
"I just want to operate as I don't have things to check off because I'm going to keep fighting to stay alive," she shared.
