Jon Jones and his fiancée have seemingly kissed and made up following his domestic violence arrest -- the UFC star just posted a video of the couple sharing a smooch on Friday ... and if the video is recent, it's clear they're moving on from the incident.
Jones shared the romantic moment to his Instagram page minutes ago ... with the song, "Stay With You" by John Legend (which we've muted for copyright reasons) accompanying the video.
Jones and Jessie Moses appear deeply in love ... smiling for the camera after the kiss.
