'Real World' And 'Challenge' Stars Unite To Honor Diem Brown

The former MTV cast members headed to Washington, DC for the Congressional Ovarian Cancer Caucus.

Stars from across the MTV family came together in Washington, DC today to support the The Ovarian Cancer National Alliance and honor the late Diem Brown.

Brown, star of "The Challenge," lost her courageous battle with ovarian cancer last year at the age of 34.

Wisconsin Congressman Sean Duffy, an alum of MTV's "The Real World: Boston" and "The Challenge: Battle of the Seasons," led the day's event -- a caucus focusing on the disease that took Brown's life.

Duffy himself reiterated Megan's message at the caucus, which was recorded as part of an upcoming MTV short-form documentary about ovarian cancer. "We need to re-energize our focus and our efforts as a society to beat this cancer. #coccnow #diemstrong," he wrote on Twitter.
