Gigi Hadid & Zayn Malik Are Still Drifting In One Direction

Zayn Malik is still rocking Gigi Hadid's boat ... and paddling it too.

Zayn gave Gigi's arms a break while the couple went kayaking Thursday during their Tahitian getaway.

We haven't seen pics of them together in weeks, but nothing puts breakup rumors to rest like a romantic luxury South Pacific vacay.
