Khloé Kardashian and Tristan Thompson Vacation in Mexico With Kendall Jenner and Ben Simmons

Though Khloé Kardashian has yet to openly discuss the status of her relationship with Tristan Thompson, the father of her daughter True Thompson (opens in new tab), the pair were spotted vacationing (opens in new tab)—and kissing!—in Puerto Vallarta, Mexico.

Khloé recently labeled her relationship status "complicated" (opens in new tab) at sister Kylie Jenner's 21st birthday party (opens in new tab) last Thursday after Kylie made special cups for her guests to choose from based on their love life. And complicated it is—considering Khloé has openly supported Tristan (opens in new tab) at his basketball games, but is also reportedly "living in hell."

We do know, however, that Khloé is enjoying sister time with Kendall, 22, and her rumored boyfriend Ben Simmons (opens in new tab), also 22, on vacation with each other. While Khloé and Tristan are loving it up in the pool together, Kendall and Ben are seemingly less affectionate, but still look very flirty on the beach. A couple other friends joined the sisters as well.

Khloé and Tristan have had a rocky history since April when a video surfaced of Tristan (opens in new tab), 27, allegedly cheating on Khloé while she was pregnant with their daughter, True. However, since then the 34-year-old has been doing her best to focus on herself by getting a new look (hello, bob!) (opens in new tab) and launching her new Good American activewear line (opens in new tab) while taking care of her daughter. Meanwhile, Kendall recently brought her modeling A-game to the cover of LOVE magazine (opens in new tab) and deserves a nice break, too.
