Kendall Jenner Says Goodbye to 2014 in Teeny Two-Piece: Bikini Body Instagram Photo

Because she can.

Kendall Jenner showed off her incredible (and insane!) bikini body while vacationing on Wednesday, Dec. 31.

Jenner, 19, posted a full-length photo of her impressive physique while standing in front of a mirror. She donned a brown two-piece and wore matching nail polish. "Dubyeeee 2014," the model wrote.

Bruce and Kris Jenner's daughter is gearing up for 2015 with Selena Gomez, Gigi Hadid, and Pretty Little Liars' Shay Mitchell in Abu Dhabi. The pals arrived to the hot desert earlier this week.

The ladies may have enjoyed a day at the beach, but it was all about sparkly dresses at night. "Guess who came matching," Gomez later captioned a pic with Hadid. "HAPPY NEW YEARS."
