World AIDS Day 2014: Prince Harry reveals secret in honor of charity

LONDON -- Britain's Prince Harry has revealed a secret -- in honor of World AIDS Day.

The fourth in line to the throne unveiled a hidden fear Monday in support of the #feelnoshame campaign being run by his Sentebale charity.

"Today on World AIDS Day, my secret is... believe it or not, I get incredibly nervous before a public speaking, no matter how big the crowd or the audience. And despite the fact that I laugh and joke all the time, I get incredibly nervous, if not anxious actually, before going into rooms full of people when I'm wearing a suit," he said.

Prince Harry co-founded the Sentebale charity in 2006 after being struck by the impact of AIDS/HIV on children and young people in the Southern African nation of Lesotho.

Throughout the day, celebrities including singer Joss Stone, actor Charley Boorman and racecar driver Daniel Ricciardo will be revealing secrets about themselves as part of #feelnoshame.

The goal is to end the stigma around the disease.

World AIDS day has been held every December 1 since 1988. It is aimed at increasing awareness of the virus and raising funds to combat its effects.
