Danielle Michelle "Diem" Brown[3] (June 12, 1980 – November 14, 2014) was an American television personality, philanthropist, and entertainment reporter.

She also founded MedGift, a web-based advocacy service that provides a gift registry for patients and support pages to both people experiencing illnesses and their caregivers.

She attended high school in Roswell, Georgia and obtained her bachelor's degree in communications from Florida State University.

Brown was partnered with Road Rules alumnus Derrick Kosinski, and the pair finished in fourth place in the competition.

Brown dated fellow Challenge castmember Chris "CT" Tamburello for over a year and a half after meeting on The Duel in 2006.

[8] The couple competed on the same team on The Gauntlet III and were featured on the MTV documentary show MADE, on which Brown aspired to learn how to salsa dance to regain her confidence.

[8] Brown ended chemotherapy in February 2013, and later competed in her seventh Challenge season, Rivals II, because she was told by doctors during her second bout with cancer that "seeing 2013 was not that likely.

[14] Two months later (August 2014), while filming her eighth and final Challenge competition, Battle of the Exes II in Panama, Brown collapsed on set, and was immediately airlifted to a New York hospital, where doctors performed emergency surgery.

In attendance were several other Challenge contestants, who came to honor Brown, whose death Duffy said “touched our MTV reality-TV family.” In attendance were Duffy along with his wife Rachel Campos-Duffy and The Real World: San Francisco castmate David “Puck” Rainey as well as Norman Korpi (The Real World: New York), Derrick Kosinski (Road Rules: X-Treme and Brown's Fresh Meat partner), and Laurel Stucky (Fresh Meat II).
