Johnny Depp's daughter Lily-Rose is growing up faster than he could have ever imagined, and as a stunning 16-year-old in the modeling industry who has publicly come out as sexually fluid, it's hard for a father to not be worried about how quickly she's becoming an adult. But that doesn't mean he isn't beyond proud of her accomplishments and courage already.

Lily-Rose took to social media in August to come out as sexually fluid, which means you do not consider yourself 100 percent heterosexual, and while many people were shocked by it, her dad wasn't fazed. At the time, it was the founder of the Self Evident Truths Project, iO Tillett Wright, who revealed Lily-Rose's involvement in the project.

"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," Wright wrote at the time, according to Us Weekly. "And I couldn't be happier to welcome her to the family. She's a tiny gem of a good human...The entire point of this project is to help young people feel good being true to themselves."

"She's got thousands of followers on social media, and they were all taken by surprise," Johnny tells Daily Mail of her revelation. "But not me. I already knew because she tells me everything - she's not afraid to say anything to me. We're super tight and I'm very proud of our relationship. And, whatever she is doing, if she needs any advice, I'm there for her. Kids are going to make their own decisions, but I guess that the only thing you can do as a parent is to offer support. And I do."

Lily-Rose is not only a budding model for major fashion lines like Chanel and Karl Lagerfeld, but she has also appeared in two comedy horror spoof films, and Johnny admits that it is a lot to process watching his baby girl grow into a young adult. 

"What's happening to Lily-Rose is something that I didn't expect to happen this early, that's for sure!" the 52-year-old actor says. "It's such a funny thing when you see your daughter transitioning from your baby, your little girl, to suddenly being a young woman. If you're not really looking for it, you can miss it, and Lily-Rose is on that road already and there's nothing I can do to stop it...When I see her with makeup and all that stuff, it's really disturbing, because she's a very beautiful girl, and it's all happening so fast."
