The "Keeping Up with the Kardashians" star took to Instagram on Sunday to debut her new hip tattoo.
In the photo, the 18-year-old shows off her red inking ... and booty. " All red. @bangbangnyc," she captioned the candid snap of her tattoo, crediting tattoo artist Bang Bang.
The new piece appears to be the word "Sanity," spelled phonetically in red ink. The mysterious body art matches the reality star's other recent tattoo, which is a small red heart etched above her elbow.Jenner's boyfriend Tyga was by her side when she got the "Sanity" piece done in New York last month.
It's been an exciting holiday weekend for the brunette beauty -- Jenner also showed off a giant diamond ring she got for Christmas.
