"Even though Kim always says, ‘Don't put a bumper sticker on a Bentley,’ I really like tattoos," she wrote.
Jenner currently has two small inkings. "They're both in white ink on my two middle fingers," she wrote.
"The one on my right hand is a full heart to represent an angel and my left is a broken heart - kind of like the devil side.
"Hailey (Baldwin) and I have matching ones on the left side but hers is red."
Jenner also revealed that she's open to the idea of getting more body art someday.
"I definitely want more eventually," she said. "I just don't know what I would get right now.
"I don't have anything in mind. You'll just have to wait and see."
