The 28-year-old Israeli supermodel's design has been done in white ink, making it even more subtle than traditional tattoos in blue dyes, reported Contactmusic.
However, fans shouldn't expect the model to be sporting a growing collection anytime soon, as she has insisted she won't make a habit of adding to her body art.
Alongside an Instagram picture of her new design, she wrote, "I finally did it. My first (and last) tattoo."
Bar had her tattoo done at a parlour in her native Israel, where she is currently staying, after celebrating the New Year there.
