When photographers asked them if they were together again, Bruce casually responded: "We've been together."
Both Kris and Bruce were wearing their wedding bands.
The duo's sighting comes seven months after Kris announced the couple was separating after 22 years of marriage and that Bruce would be moving to his Malibu home permanently.
"We ended a marriage, but that's not the end of our friendship," she said at the time. "I will always love him, but we are no longer a couple in that way."
