Friends through thick and thin!
Alongside a picture of the gal pals hugging (above), the 39-year-old wrote:
"My #mondaymuse (and really every day #muse) is my brave friend@theshando. 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. That's a true friend #FuckCancer"
We're sure Shannen appreciates being surrounded by so many loved ones during such a difficult battle.
We continue to pray for a speedy and successful recovery!!!
