Rupert Sanders Reunites With Wife After Kristen Stewart Affair News

Cameras snapped away after Liberty Ross and Rupert shared a meal at Judi's Deli. It's unclear who paid ... or how long they sat ... but we're guessing it couldn't have been a fun convo.

As we previously reported, Rupert is still wearing his wedding ring ... and is hopeful he can work things out with the mother of his children.

Liberty, on the other hand, had NO RING on her finger when she was spotted out in L.A. yesterday.
