The 15-year-old appears alongside her brother Jaden, 18, in the September issue of Interview magazine, for which they sat down for a chat with Pharrell Williams, and Willow admits she has always looked up to their parents.

"Growing up, all I saw was my parents trying to be the best people they could be, and people coming to them for wisdom, coming to them for guidance, and them not putting themselves on a pedestal, but literally being face-to-face with these people and saying, 'I'm no better than you, but the fact that you're coming to me to reach some sort of enlightenment or to shine a light on something, that makes me feel love and gratitude for you,'" Willow recalled. "They always give back what people give to them."

Jaden echoed his sister's thoughts, adding: "I 100 per cent agree with Willow on that one. My parents are definitely my biggest role models. And that's where me and Willow both pull all of our inspiration from to change the world. It all comes from a concept of affecting the world in a positive way and leaving it better than it was than when we came. I feel like that enters into all types of different areas because there are so many different outlets that life has to offer for us. That goes into technology, into music. That goes into science, into spirituality, into education."

Both Willow and Jaden are very active on social media, and frequently use it as a medium to get across their latest campaign. And one thing the pair can always be sure of is that they are being their true selves - something that is severely lacking on many online profiles, according to Willow.

"I know so many kids who literally are, like, Instagram-famous. They have done nothing but post pictures on Instagram," Willow said. "And they have followings. People love to see them in person, but it's only because they post on their Instagram. It's literally crazy. Kids will paint a picture of themselves that is so far beyond who they actually are. It's like they're wearing someone else's skin."

Jaden concurred, proving the pair's incredibly close bond transcends into their beliefs and thoughts on a daily basis.

Speaking about their connection, Willow admitted she finds it "crazy" that she loves her brother so much.

"It's crazy, the sibling dynamic," she remarked. "Throughout us realising ourselves and realising each other, we just opened our eyes and were like, 'Damn, you are the yin to my yang.' Not a lot of siblings have that opportunity, because they're always being pushed together so much. They need their time apart in order to realise themselves and realise who they are."
