Kendall Jenner & Harry Styles -- All Hands On Deck (PHOTOS)

Kendall Jenner and Harry Styles became extra familiar with each other on a luxury yacht in St. Barts.

The two were spotted Wednesday getting handsy after reports surfaced they'd been vacationing together in Anguilla the night before.

It's unclear if the two are "officially official" but judging by the pics, the 20-year-old supermodel and 21-year old pop star certainly have no problem packing on the PDA.
