Kylie Jenner at Same Club as Her Sisters' Exes Ben Simmons, Tristan Thompson
Kylie Jenner My Sisters' Exes Mark the Spot ... Tristan, Ben Show Up at Same Club

So, the ex-boyfriends of Khloe Kardashian and Kendall Jenner walk into a bar, but Kylie Jenner's already there -- there's no punchline here, just a weird night in West Hollywood.
Kylie was hanging out inside Delilah nightclub well after midnight Thursday morning when NBA stars Tristan Thompson and Ben Simmons rolled in shortly before 2 AM ... aka closing time.
They didn't stay too long -- 5 minutes later, Simmons bolted ... maybe because he saw Kylie, maybe because it was closing? A few minutes later, Kylie and Tristan took off too ... separately, mind you.
Unclear if Kylie had any interaction with Kendall and Khloe's ex-BFs, but as they say ... Hollywood's a one-horse town.
As you know ... Khloe and her baby daddy had a major falling out in February when Kylie's BFF, Jordyn Woods, hooked up with him. And, Kendall and Ben reportedly broke up a few weeks back.
As an added bonus, French Montana -- who also dated Khloe in 2014 -- was at the club too, but left right before Simmons and Thompson arrived.
Almost like it was a fraternity meeting.
