The Duke of Cambridge has revealed he is to feature in the next issue of the UK's leading gay magazine Attitude.
William mentioned his magazine debut during a visit to the American Embassy to sign a book of condolence for victims of Sunday's gay nightclub shooting in Orlando.
After signing a message, he and the Duchess of Cambridge spoke to staff who have worked on LGBT issues, which is when William let slip his forthcoming magazine appearance.
"I told him what I do and he said he's going to be in Attitude magazine," Craig Petty said.
Mr Petty, who is president of LGBT association Glifaa, praised the royals for offering their public solidarity in the aftermath of the Florida massacre.
"I think it's great that they have come here today to show their support," he said.
The next issue of monthly magazine Attitude is due for publication on Wednesday.
The magazine's managing director Mike Buckley confirmed William's appearance and said: "We will have some exciting announcements to share soon."
A Kensington Palace spokesman said: "We look forward to speaking about this soon."
