It feels as though we’re in the midst of a revolution. Over half of UK youth do not identify as straight, a lot of Grindr users say that they aren’t gay and earlier this summer, Miley Cyrus refused to label her sexuality.

The latest person to lend their name to the new wave is 16-year old model and actress Lily-Rose Depp, daughter of Johnny. iO Tillett Wright is a self-styled "artist, social scientist and photographer" and a friend of the model whose project is Self Evident Truths, a campaign to take the photo of 10,000 people who identify as anything other than 100 per cent straight.

"This project exists to spread awareness and understanding about a broader spectrum of human sexuality," she says. "We want to bring human stories from within the LGBTQ community to the world, so that we can begin to erase the boundaries between “Gay”, “Trans”, “Straight”, and “Other”.

Yesterday, she Instagrammed a picture of herself giving Depp a piggyback along with the caption, "She decided to wanted to be in Self Evident Project because she falls somewhere on the vast spectrum, and I couldn’t be happier to welcome her to the vast family."

Last year, Cara Delevingne also used Self Evident Truths and Instagram to reveal that she does not identify as heterosexual.

Earler this year, Depp landed her first campaign for Chanel, brought on board by Karl Lagerfeld, who described her as " a young girl from a new generation with all the qualities of a star".

Tillett Wright hopes to capture the increasingly liberal attitudes of this new generation with Self Evident Truths. Watch her discuss the personal photo project below:
