Prince William has appeared on the cover of the UK gay magazine, Attitude, to speak out against bullying people because of their sexuality.

The second-in-line to the throne is the first member of the royal family to appear on the cover of a gay publication.

He told the magazine that no-one should be bullied for their sexuality.

It's editor Matthew Todd said it's a major sign it's okay to be part of the LGBT communities.

"Prince William is from the highest institution in the land. He will be the King of the United Kingdom at some point we all hope, so you can't get higher than that."

William revealed his magazine appearance after signing a book of condolence for victims of the gay nightclub shooting in Orlando which left 49 people dead and dozens wounded.
