Meghan Trainor -- Off into the Sunset ... With DeAndre Jordan?!!? (VIDEO)

Singer Meghan Trainor obviously didn't get too tangled up with Charlie Puth after the AMAs ... because she seemed tight Saturday night with L.A. Clippers center DeAndre Jordan.

Meghan and DeAndre hung out at The Nice Guy in West Hollywood, and then got into the same car and drove off together.
