Kylie Jenner, 18, and Tyga, 25, continue to pack on the PDA as the hold hands while jetpacking in St. Barts

They were pretty hush hush about their relationship until recently.

But Kylie Jenner, 18, and her beloved beau Tyga, 25, certainly aren't shy about packing on the PDA anymore.

The two could hardly hide their affection on Wednesday, as they jetpacked in the turquoise waters of the luxurious Caribbean island of St. Barts.

 

The doting duo appeared ecstatic while embracing each other on the water, spotted smiling wide and holding hands as they balanced on special water boots that propelled them up in the air.

Kylie and Tyga looked keen on staying close, reaching their arms out for one another when distance kept them apart.

But the pair aren't the only ones to have enjoyed thrilling water activities, as Kylie's sister Kendall, 19, was previously pictured on a water-powered jetpack.

Much of the Kardashian and Jenner clan are on the French island of Saint Barthélemy to film the new season of E!'s reality TV series, Keeping Up With The Kardashians.

Tyga seems to have found his place with the famous family and it's even more clear since Kylie legally became an adult on August 10.

When he first started hanging out the family last year, the Faded hitmaker was engaged to model/stripper Blac Chyna, mother of his son King Cairo, who was born in October 2012.

Kylie and the father-of-one finally went public with their romance when they were spotted holding hands in Mexico last week celebrating the teen's milestone birthday.

Meanwhile, the daughter of Kris and Caitlyn Jenner revealed a new tattoo on her arm in the form of a dainty red heart when she partied in Montreal, Canada on Sunday - following their Mexican getaway.

Tyga is covered in inkings including Kylie's name marked on his right forearm.
