Paris Jackson just got matching tattoos with her brother Prince Jackson, marking their devotion to each other.

Paris is truly the yin to Prince's yang. The siblings showed off their new matching tattoos on Instagram this week, along with very touching captions. Paris and Prince got corresponding halves of the yin and yang symbol, as seen below:

The 18-year-old daughter of Michael Jackson explains exactly what the symbols mean and how they represent their bond.

 /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!
