On Saturday the Keeping Up With the Kardashians star and the Cleveland Cavaliers player decided to take their rumored romance to the high seas where they each hopped on a jet ski and rode the waves. Khloe stunned in a Baywatch-style red monokini, while Tristan kept it cool in a white tank top and purple swim shorts. Khloe's BFFs Malika Haqq and Khadijah Haqq were also spotted getting in on the water fun.
The group was spotted at Mandala nightclub Friday, where they stayed for two-plus hours and took some shots with a few ladies. But an eyewitness told E! News that while Khloe and Tristan were "laughing a lot," there wasn't any "kissing or holding hands."
Saturday night, however, that all changed. Khloe, Tristan, Khadijah and Malika all returned to Mandala nightclub where Khloe and Tristan were spotted participating in some PDA.
"They kissed a couple of times and held hands," the eyewitness said. "They looked happy and were having a good time."
Although another source told us that these two are just friends, this latest development won't stop fans from further speculating that they could be an item.
In addition to Khloe and Tristan's jaunt to Mexico, they were also spotted at a Beverly Hills mansion last Thursday. E! News also confirmed that Khloe and Tristan were at Bootsy Bellows in West Hollywood earlier in the month where there was "no visible PDA."
While Khloe continues to vacation in Mexico, Kourtney Kardashian headed to Italy for a last-minute trip with Kris Jenner and Corey Gamble. Kim Kardashian, on the other hand, is spending time with her kids, Saint West and North West.
