The 18-year-old singer and her 15-year-old sibling - who are the children of the late music legend Michael Jackson - decided to get the inking of the symbol, which is known in Chinese philosophy to mean balance, on her ankle because they share the "same thoughts", and although they may be "totally opposites" their contrasting personalities enable them to "work together".

The blonde beauty shared a picture of the body art on her Instagram account, which she captioned: "/yin/ [in Chinese philosophy] the passive female principle of the universe, characterized as female and sustaining and associated with structure, night, the moon, fluidity, calmness, the earth, darkness, cold, death, and ascends energy. /yang/ the active male principle of the universe, characterized as male and creative and associated with function, the sky and sun, speed, expression, heaven, heat, light, birth, and descends energy.

"sometimes i feel like my big brother and i always think the same thoughts, he just doesn't have a filter and always vocalizes them though total opposites, like my gooko and i, the inseparable yin and yang work together finding and causing balance within each other. matchies with my bestie @princejackson! (sic)."

And Prince believes the tattoo is to prove the pair are inseparable and will always be together.

Alongside the same image, which he shared on his photo-sharing site, he wrote: "You are with me and I am with you (sic)."

However, this is not the first piece of work etched onto the California-born star's body, as she also has a sunflower printed on the back of her left forearm, a variety of stars on her hands, a wolf on her wrist, and a musical note merged into a heart on her neck, as well as many more tattoos.
