Kylie Jenner took to Instagram on Wednesday, August 10 to show off her bikini body. The reality TV star who turned 19 that day channeled her inner "Baywatch" in a cleavage-baring red one-piece and a skimpy bikini.

In the first picture, Kylie showed off her red cornrows while posing in a sexy red swimsuit in her bedroom. She completed her look with a gold choker, delicate body chain, rings and furry slippers. She simply captioned it with a heart emoji and "19".

Kylie, who is vacationing in the Bahamas alongside Tyga, Kendall Jenner and pals like Bella Hadid and Hailey Baldwin, later shared some photos from their yacht outing. The birthday girl frolicked with her sister and gal pals on the beach.
