When they got back to shore, Kuzma was spotted at a house party with Kendall.
The whole thing begs the question ... are they dating?
Back in February, 23-year-old Kuzma was linked to Katya Elise Henry ... a model with nearly 6 million followers on IG. Funny enough, the two were also hanging on a boat together earlier this year!
Kendall has since left the country -- she's currently hanging out in thong bikinis with her model friends in Greece. Again, good times!
Kuzma has had a crazy off-season -- he was essentially the only one of the young Lakers players who wasn't traded away in the Anthony Davis deal.
Kuzma was a 1st-round pick in the 2017 NBA Draft and has become a breakout star for the Lake Show. He's entering the 3rd year of his rookie contract (3 years, $5 mil) ... so he's gonna get PAID real soon!
