MTV reality star Diem Brown died Friday after a prolonged battle with cancer, Us Weekly reports. She was 32. An entertainment reporter and participant on the long-running show The Challenge, Brown also founded MedGift, a crowdfunding site that helps those undergoing medical treatment.

On Tuesday, as her condition worsened, Brown reached out to fans on Instagram and Twitter, writing: "I NEED prayers and advice. My doctors are seemingly giving up but I won't & can't roll over. Whatever option I have to LIVE I'm grabbing." Brown was scheduled to undergo another round of chemotherapy next Tuesday in the hopes of shrinking the tumors.

Her friend, E! correspondent Alicia Quarles, remained by her side, and echoed Diem's plea on her own Instagram, writing, "We both believe in the power of prayer. She's asked that I ask all of you to pray for her. God is good. Diem would like a huge prayer circle. I reassured her she has one. Diem smiled and told me, a little reminder never hurts."

This was Brown's third cancer diagnosis after being previously diagnosed with ovarian cancer in 2006 and 2012. As she told Us, this time the cancer spread to her colon and stomach lining; but she remained in high spirits, saying, "I'll beat cancer again. I'm a warrior."

The Georgia-born personality rose to fame in 2006 with her debut appearance on MTV's Real World/Road Rules Challenge: Fresh Meat and went on to compete in six more versions of the competition show.

Brown's own battle with cancer inspired her to start MedGift, which created both a financial and emotional support network for those grappling with health issues. While Brown never intended to use the site herself, Quarles and Brown's family started a page in her honor following her most recent diagnosis.

She is survived by her father, brother and two sisters.
