Kendall Jenner's giant Calvin Klein Jeans billboard in New York City is in rough shape.

The billboard featuring the 19-year-old supermodel that sits at a busy intersection in NYC was vandalized on Wednesday, Entertainment Tonight reported.

The culprit? KATSU, a notorious graffiti artist and vandal, who posted a video of the act on YouTube.

KATSU admitted he used a hacked Phantom drone to paint red lines all over Jenner's face.

"It turned out surprisingly well," KATSU told Wired "cheerfully," according to ET. "It's exciting to see its first potential use as a device for vandalism."

KATSU reportedly said the process to blemish the billboard, which is about six stories tall, was "very tense" but only took a matter of seconds to complete.

It's probably safe to say Jenner, a star on Keeping Up with the Kardashians, is upset with what went down because she had told ET earlier this month it was her "dream" to be displayed on something so large -- a truly "surreal" experience.
