ICYMI, sixteen-year-old model Lily-Rose Depp came out as 'sexually fluid' on Instragram yesterday (August 25), joining Miley Cyrus, Cara Delevingne, and Kristen Stewart in the ranks of bad-ass, famous young women -- not to mention half of all young people in the UK, according to a recent poll -- who've made it clear that their sexuality is vast, complex and definitely not 100 percent straight.

Lily-Rose posed as part of the Self Evident Truths project. Artist iO Tillett Wright is photographing the faces of 10,000 Americans who identify as "not 100 percent straight," ("even 1% gay!") with plans to exhibit the entire photo series on the lawn of the White House sometime before the 2016 election.

"I'm so proud of my baby girl @lilyrose_depp," Wright wrote in the Instagram caption for Lily-Rose. "She decided she wanted to be in @selfevidentproject because she falls somewhere on the vast spectrum, and I couldn't be happier to welcome her to the family. She's a tiny gem of a good human."

Cara Delevingne also posed for the series earlier this year (as did Rosie O'Donnell), and Miley Cyrus, though she hasn't posed for this particular photo series, has been very open about her own sexual fluidity.

According to the Self Evident Truths project website, the goal of the project is to help stop discrimination against the LGBT community by showing that some degree of sexual fluidity is actually pretty common in Americans, and that ultimately, we're all still humans. Wright has been working on the project since 2010, and has already photographed the beautiful faces of 9,958 "not 100 percent straight" people across the country.

Wright says she first started the project because she was "stunned" by the fight that happened in California in 2010 over the Prop 8 gay marriage ban. She "started to ponder where the real disconnect was between gay Americans and those voting against them and she decided it was an issue of fear. Unfamiliar with the realities of gay life and bombarded with misinformation, conservative voters are misinformed about what it means to be gay, so she decided to introduce people to each other."

"The aim of the project is to humanize a vast community through the simplicity of their faces," the project's website explains, "showing that we come in all shapes, sizes, races...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.'"

Wright has also given a powerful TEDx talk on the importance of giving human faces to the vast spectrum of human sexuality called, fittingly, "Fifty Shades of Gay."

After the photos are exhibited in DC, Wright plans to release a mini-documentary series and a book of the portraits. She also plans to open the Self Evident Truths website to uploads, so people she didn't get to photograph can put up their own pics and keep the project going indefinitely.

...Is it too early to start taking selfies for this now?
