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?
