It has been reported that reality TV star Diem Brown has passed away.

Diem, perhaps best known for her role on MTV’s The Challenge, had been battling cancer on and off for almost a decade.

Last month, the 32-year-old opened up on her heartbreak upon learning that the cancer had spread, telling People that the news “crushed a little bit of my spirit”.

In an inspirational Twitter post from three days ago, Diem wrote: “I need prayers and advice, my doctors are seemingly giving up but I won’t and can’t roll over. Whatever option I have to LIVE, I’m grabbing!”

Indeed, throughout her treatment, Diem promised to fight through her illness, recently writing on Instagram: “I’m not taking no for an answer…We know there is hope and help. We need you.”

Diem was diagnosed with ovarian cancer back in 2008. While she went into remission after treatment, the disease returned in 2012.

Such very sad news. Our thoughts and prayers are with her family.
