The possibly-on-again couple arrived together at The Abbey in West Hollywood Saturday around 1 AM. We're told they had some drinks and danced with a few friends.
It looks like they really enjoyed grooving to Cardi B's "Bodak Yellow."
You may recall ... we last saw Elon and Amber smooching after a lunch date in L.A. a few days before Christmas. We thought it meant they were back together, but a source close to Elon told us they weren't.
