Khloe Kardashian and Tristan Thompson were spotted on a double date with Kendall Jenner and her new man Ben Simmons last night, which marked the first time the new mom was spotted out and about in Los Angeles since the birth of her daughter True on April 12.

Noticeably absent from the outing were sisters Kim, 37, Kourtney, 39, and Kylie, 20, who as Breaking Celebrity News has reported, can't stand cheating Thompson for betraying Khloe just days before she gave birth.

Now, according to a Keeping Up With the Kardashians insider, the other sisters "think Kendall hanging out with Tristan is f****d up."

However, “Kendall and Khloe don’t care what their sisters think, and they never really have,” the insider claimed.

As Breaking Celebrity News readers know, Kendall, 22, started dating NBA star Ben Simmons while he was allegedly still with singer girlfriend Tinashe. She was also accused of breaking up ex Blake Griffin from his baby mama.

“Kendall understands cheating from all angles,” the source told Breaking Celebrity News. “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.”

Kendall and Khloe, 33, also relate to being sick and tired of Los Angeles and the Hollywood lifestyle.

Though they are both in L.A. right now, "neither of them like L.A. Kendall just hasn’t felt safe there ever since her stalker incident and Khloe hasn’t been happy there even before falling for Tristan.”
