Kim, wearing a revealing halter top, was also joined by pals Jonathan Cheban, Lala Anthony and Simon Huck – as well as a Keeping Up With The Kardashian film crew.
“Cameras were filming the dinner!” a source told Radar Online. “Tristan showed up about halfway through the dinner. He joined the table and stayed until they were all done.”
Despite Kim and Tristan’s well-documented feud, the pair seemed to be getting along.
“He was laughing and joking with everyone and it wasn’t awkward looking at all. Khloe wasn’t there, but the cameras filmed it. Tristan and Kim talked all night, and he joked around with Jonathan,” said the eyewitness.
