Wednesday may have been Kylie Jenner’s 19th birthday, but she wasn’t the only one in the limelight. Bella Hadid jetted off to Turks and Caicos with Kylie and Kendall Jenner for the occasion and showed off her killer curves in a denim string bikini.

The model took to Instagram to share a sexy swimsuit shot of herself sitting on the rail of a boat over the blue water (above). Hadid looked fierce in a high-cut denim bikini, her hair pulled up into a bun, and a pair of orange Quay Australia shades ($55;

The 19-year-old also posed on the beach with her friends Kendall and Hailey Baldwin, who posed for a cheeky snap, and enjoyed the Caribbean sun on the back of a boat.

Of course, the model sent her best wishes to the lucky birthday girl. “Happy birthday Ky Baby. ... life would be boring without you,” she captioned a cute photo in which Kylie gives a wide smile as she runs toward the camera on the beach.

It looks like Kylie certainly enjoyed her big day.
