Born into enormous wealth and celebrity, one could expect Brad Pitt and Angelina Jolie's twins Knox and Vivienne Jolie-Pitt to succumb to the all-consuming world they've been brought up in.
But despite their immense privilege, the siblings, now 12, have grown into independent and unique tweens determined to pave their own path.
"Viv has said she wants to be a humanitarian and philanthropist," a source tells Woman's Day.
"Meanwhile, Knox is interested in becoming a tech engineer and developing software," our source adds.
While the twins have every entertainment contact at their disposal, the insider says they're heavily focused on more unique hobbies.
"Viv has a black belt in karate and can hold her own against the boys," the insider reveals.
"She likes gender-neutral outfits, like sweatshirts and jeans, and an edgy, choppy haircut. She'll go to a movie premiere, but she'll dress tomboyish."
"Knox is extremely creative and many of his drawings have been converted into jewellery. He's even been learning sign language while his twin sister studies Arabic."
Despite the children's extraordinary lifestyle, parents Brad, 56, and Angelina, 45, are determined to help them – and their siblings Maddox, 19, Pax, 16, Zahara, 15, and Shiloh, 14 – stay as grounded as possible.
"The children are surrounded by wealth, but they're still just kids who like video games and graphic novels, skateboarding and pet stores," the source adds.
