AceShowbiz - It looks like having fun at Kylie Jenner's star-studded birthday bash isn't enough for Khloe Kardashian and Kendall Jenner. The two sisters jetted off to Puerto Vallarta, Mexico with Tristan Thompson and Ben Simmons over the weekend. During their fun-filled getaway, the group stayed at Casa Aramara, the famous family's favorite villa.

On Sunday, August 12, the foursome were spotted soaking up the sun at their villa. Khloe and Tristan did not shy away from flaunting PDA on that day. The couple were photographed taking a dip in the pool where she wrapped her arms around her man and kissed him. Afterward, they filmed their makeout session when they were out of the pool.

In contrast to her sister, Kendall decided to keep it low-key as she and her alleged boyfriend were only seen lounging on chairs nearby. They also hit the beach and rode Jet skis together with Tristan. Kendall flaunted her stunning figure in a bright blue bikini, while Khloe wore a black one piece and a brown hat.

On the previous day, the group partied together at Puerto Vallarta hotspot La Santa, where Khloe posted a video of Tristan kissing her on the forehead while dancing to the music.

It arrived after Khloe hinted that her relationship with Tristan was "complicated" at Kylie's birthday party, where guests were asked to choose a cup color based on their relationship status. She was seen carrying a green cup, which meant, "It's complicated." However, the "Revenge Body with Khloe Kardashian" host has set the record straight on the speculation.

In response to a fan's question on Instagram about the matter, she replied, "People are reaching. I ordered a drink, it came in a cup, I drank it. End of story. Not that deep lol. I'm sure I drank out of every colored cup that night."
