Television personality Nick Brown, cast member of MTV's The Real World XX: Hollywood and who will appear April 8 as a contestant on MTV's Real World/Road Rules Challenge: The Duel II has organized an online auction to benefit the Cancer Research Institute.

"Many fans who watched The Real World saw how devastated I was when I learned that my mentor and friend, Brandon Schantz, lost his battle to lymphoma at age 27," says Brown. "I wanted to do something in memory of my friend that would help other people battling cancer."

Nick enlisted the generosity of other reality T.V. stars, including Dave Sky (Real World: Hollywood), and Will Gill of Michigan State (Real World: Hollywood), to donate items they won on the game show or otherwise are known to have worn on television.

Proceeds from this online auction, which will be hosted on eBay, are going to be shared between the Cancer Research Institute and the Brandon Schantz Memorial Endowment Fund at the University of Texas College of Communications.

Bidding concluded Thursday, April 16, at 5 p.m. EST.
