4. There is no competition between them:

Jaden: We never really felt competitive because Willow’s always been better than me at everything. There’s been no competition.

Willow: [laughs] Pharrell, that is so not true.

Jaden: Willow started making music first. I was like, “My younger sister is, like, 4, and she’s making all these fire songs. What’s happening?” Willow was doing all these things, about to have record label deals at like the age of 6, and I was like, “I feel like I’m underachieving.” That was around the time that I was doing Karate Kid, and I could do flips, and I thought I was special because I could do flips. But Willow could do the flips, too! Willow naturally had it. Like, I was trying to do no-handed cartwheels. Willow had it. I was trying to get to the studio. Willow was in the studio. You know what I’m saying? Willow just didn’t have as big as a passion for acting as me. But if she did, she could do what I did. So there’s always been competition, but we’ve always worked as hard as possible to do the things that we want to do. We never got upset because we could always do the same thing. It happened so that me and Willow were able to go through every level or different section of life that we wanted to. If we wanted to act, we could act. If we wanted to dance, we were dancing. And we could do it on the level that we wanted to do it. So there was no, like, “I’m mad at you.” Well, we would get mad at each other when we were young, but that stopped when we were, like, 9.

5. They had more fashion sense when they were much younger:

Willow:: Me and Jaden, when we were younger … [laughs] Ooh! We would wear the craziest things. Jaden would only wear his Spider-Man costume. I would freaking mismatch every single shirt and pants in my closet. We would just be so rambunctious with our clothing choices. And when we were old enough to start dressing ourselves, my mom was like, “Are you sure you want to go out like that?” And me and Jaden would be like, “You know what? Yes.” And she’d totally accept it. I feel like that’s where most of our confidence comes from. Because we weren’t told, “Oh, you don’t look good in that. You look crazy. People are gonna think this about you.” Like, obviously, that was going to be happening regardless, but it wasn’t like that ruled what we did or the choices that we made.

Jaden: Nobody knows that Willow and I were much, much cooler before. Like, before people were looking at the things that we were doing, we were so much more, like, method with fashion. We really went all the way. We went the extra mile on everything because there was no one looking at us. We’ve been through the roof, with ludicrous fashion ideas since we were extremely young.
