Exes Justin Timberlake and Cameron Diaz reunited Friday night at the Whisky Bar in the Sunset Marquis Hotel in West Hollywood.

J.T was dining out with Academy Award winning director Martin Scorsese and eight other guests at a table inside the hotel’s exclusive bar. Wearing a striped coat, Justin briefly chatted with the legendary screen director.

Cameron popped up at around 1 am:

“Cameron never joined their table,” says a nearby snitch. “She just showed up and Justin got up and started talking to her. They were being very discreet.

“They weren’t kissing or holding hands or anything, but they were being very friendly,” the observer adds.
