AceShowbiz - Kendall Jenner fuels dating speculation with Ben Simmons after they were spotted grocery shopping together. The rumored lovebirds were photographed enjoying a date night with Khloe Kardashian and Tristan Thompson in Los Angeles on Monday night, June 18.

An insider told E! News that the group attended Dave Chappelle's family and friends-only private show at the Peppermint Club, where they were seated together. Kendall and Ben were said to be cuddling next to each other and laughing together while watching the stand-up comedian perform onstage. Meanwhile, Khloe and Tristan were "very affectionate," kissing and laughing during the show. The source noted the Canadian athlete was protective over his girlfriend that night.

Anwar Hadid, who was caught on camera making out with Kendall, was also in attendance along with someone else. The insider claimed he and Kendall did not have an awkward run-in. Instead, they casually greeted each other and were friendly.

Once the comedy show was over, Khloe and Tristan headed to Poppy nightclub where Dave hosted a private after-party. The "Revenge Body with Khloe Kardashian" host and her athlete boyfriend looked affectionate and hung out with other guests at the party, according to the insider. Kendall and Ben didn't join them at the bash.

While the four appeared to be having fun that night, the other Kardashian sisters were not happy about their double date. A source close to the sisters tells Radar Online that they "think Kendall hanging out with Tristan is f***ed up."

However, "Kendall and Khloe don't care what their sisters think, and they never really have," according to the source. "Kendall understands cheating from all angles," the source adds. "She is into Ben, and it just so happens that him and Tristan are tight. The way Kendall sees it, as long as Khloe is happy then she is happy for her."
