Johnny Depp's daughter Lily-Rose Depp reportedly doesn't completely identify as ''100 percent straight.''

The 16-year-old actress, whose mother is French singer Vanessa Paradis, decided to take part in a new photo-shoot for photographer iO Tillett Wright's Self Evident Truths Project, which is attempting to capture the images of ''10,000 people in the USA that identify as ANYTHING OTHER than 100 percent straight,'' because she ''falls somewhere on the vast spectrum.''

The activist shared a photograph of the teenager on Instagram, with the caption: ''I'm so proud of my baby girl @lilyrose_depp. 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. #prouduncle #weareyou.''

Lily-Rose and her parents have not yet commented on her involvement in the LGBT [Lesbian, Gay, Bisexual and Transgender] campaign, which model Cara Delevingne, 23, also previously posed for.

A source close to teenager recently claimed she has been turning to her mother for career advice because she thinks Johnny is ''way too protective.''

The insider said: ''Vanessa is more encouraging of her wild, artistic side, and she already has a major studio in love with Lily. ''

The starlet, who was born in Paris, recently completed shooting 'Yoga Hosers' alongside her father, and recently signed on to appear in the upcoming film 'Planetarium'.

It was also announced she will star in comedy 'Moose Jaws' next year.
