Is Khloe Kardashian dating another NBA star?

The “Keeping Up with the Kardashians” star fueled romance rumors with Tristan Thompson after the two traveled to Mexico together for the Labor Day weekend. According to People, the rumored couple jetted off to Cabo San Lucas on Thursday, Sept. 1, and was reportedly spotted around the town on Friday evening.

An onlooker told E! News that the 32-year-old reality TV star and the 25-year-old Cleveland Cavaliers power forward accompanied actress Malika Haqq to Mandala nightclub. Although Kardashian and Thompson were reportedly “laughing a lot of the time” while in the club, the eyewitness said that there were “no kissing or holding hands” that had happened between the two.

This wasn’t the first time Kardashian and Thompson were spotted together. As TMZ reported on Friday, Kardashian and Thompson were also seen at Bootsy Bellows nightclub in Beverly Hills, Calif., last weekend. The website noted that they left the club within minutes of each other.

E! News confirmed TMZ’s report, adding that there was “no visible PDA” between Kardashian and Thompson during the night out.

Despite all the recent sightings of the duo, another source told E! News that they are “just friends” and not in a romantic relationship with each other.

Kardashian is technically still married to Los Angeles Lakers player Lamar Odom, whom she wed in September 2009. Kardashian filed for divorce from the athlete in December 2013. She, however, withdrew her pending divorce petition after Odom was found unconscious in a Nevada brothel last October. In an interview with People that same month, Kardashian clarified that they had not reconciled, and the divorce had just been withdrawn so she might make medical decisions on Odom’s behalf.

Kardashian also dated James Harden, shooting guard for Houston Rockets, from June 2015 to February 2016.
