Diem's MTV Co-Stars React to Her Passing

Today is a sad day for those who loved and admired reality star and cancer fighter Diem Brown. The amazingly strong and positive woman who fought so bravely during her battle with cancer died Friday morning at the very young age of 32. Throughout her battle, Brown never gave up and continued to fight for herself and others suffering from the horrible disease. No matter the struggle, or if she was having a bad day, Brown looked at the glass half full and promised herself and others that she would never give up. She was one beautiful woman, inside and out, who will continue to touch the lives of so many.

Her death is hitting home for many people, especially her fellow Real World Road Rules Challenge co-stars. Some have taken to social media to express their sorrow, grief, and heartbreak over Brown's too-soon passing. Even through a short 140 characters, you can see how Brown influenced and impacted their lives. She truly was an incredible woman.

Here's what some of them, including Coral Smith, Chet Cannon, veteran Mark Long, and Once Upon a Time actress Jamie Chung (who got her start on The Real World: San Diego) are reflecting about this very special woman.
