Kim, 38, rocked a glitter halter top and leather pants as she headed out of The Real Real magazine offices to catch up with her former enemy at dinner.
As Kim gathered her pals for the awkward get-together, Keeping Up with the Kardashians cameras were ready nearby.
“Cameras were filming the dinner!” said a Radar eyewitness. “Tristan showed up about halfway through the dinner. He joined the table and stayed until they were all done.”
Though RadarOnline.com readers know Kim and Tristan, 28, have never gotten along, the source said they seemed comfortable with one another during the outing.
