Kendall Jenner and Ben Simmons -- Round 2?!?!?
Sure seems like it, because the two got together for some private 1-on-1 time after the 76ers played the Clippers in Philadelphia this week ... and we've got the video.
Remember, Kendall and Ben broke things off in September after she was spotted kissing Anwar Hadid in a nightclub ... despite being in a relationship with Simmons for months.
It appeared the two had moved on -- until Thursday night, when Kendall showed up at Ben's game at Wells Fargo Center.
