In a surprising turn of events, Kim Kardashian and Tristan Thompson, the ex of her sister Khloé, were recently spotted partying together in Miami, Florida. The duo attended Lionel Messi's soccer match before heading to the celebrity hotspot Gekko for dinner and then to the LIV nightclub, where they partied late into the night alongside DJ Khaled.

Kim, dressed in an all-black leather outfit, and Tristan, sporting a sheer black button-down and black satin pants, were also joined by David Grutman and his wife, Isabela Rangel. The NBA star shared glimpses of their fun night out on his Instagram Story, which has since sparked a wave of speculation and criticism from fans.

Many fans took to social media to express their confusion and disapproval over the outing. Some questioned the nature of Kim's relationship with Tristan, with one Twitter user asking, "Is she banging her sister's baby daddy?" Others suggested that Kim might be involved with a basketball player and that Tristan is merely a diversion.

Despite the criticism, both Kim and Tristan have remained silent on the matter. This is not the first time the pair have been seen together in public. In May, Kim and her daughter North were seen holding a hand-painted sign that read "Tristan Thompson" at one of his games against the Golden State Warriors. They were also spotted together during a "Friendsgiving" last November when they visited a Los Angeles juvenile detention facility.

While there is no confirmation that Kim and Tristan are anything more than friends, their frequent public appearances together have certainly raised eyebrows. However, as of now, their relationship remains unclear, and they have not addressed any rumors or speculation.

As previously reported, Khloé, who has a son with Tristan, has managed to maintain an amicable co-parenting relationship with him despite their tumultuous past. The recent events, however, have added a new twist to the ongoing Kardashian-Thompson saga, leaving fans and observers eagerly waiting for more clarity.
