Prince Harry has revealed his biggest fear during a campaign for his Sentebale Charity to mark World AIDS Day. In his video for his #FeelNoShame Twitter campaign, he explains what makes him really nervous.

The Guardian reported that the Prince and other celebrities had vowed to help people all over the world have the courage to share their deepest secrets without the feeling of shame, hence the hash tag #FeelNoShame for the Twitter campaign.

Some celebrities, like Ricky Hatton, admitted to being “petrified” of cats; Joss Stone apparently likes to use service station bathrooms; and Gemma Arterton never saw Star Wars. Cue every Star Wars fan clutching their hearts in shock.

Prince Harry’s reveal, well, wasn’t too climatic, as he revealed his secret is “I get incredibly nervous before public speaking, no matter how big the crowd or the audience.” He joins the ranks of other people, around 75%, who have glossophobia, which is the fear of speaking in public.

As a royal, it is his responsibility to speak in public, so it must take a lot for him to get through his duties, but he has done it well.

Us Weekly reported he made the video announcement while wearing casual clothing. While it isn’t as huge a secret as revealing you have AIDS, it can be hard to admit secrets like this.

He also said in the video, “Now that I’ve confessed that, I’ll probably be even more worried that people are looking at me. But, thank you very much for everyone who’s taken part, and I must encourage as many people to get involved as possible.”
