Talk about an unexpected dinner date.

Seven months after announcing their split and nearly two weeks after their divorce was finalized, Ryan Reynolds and Scarlett Johansson seemed to put the past aside as they dined together at L.A.'s Little Dom's restaurant Saturday night.

"They were leaning in closely to each other when talking," a source at the restaurant tells PEOPLE. "They were being flirty."

Their intimate dinner comes amid reports that Reynolds, 34, has been seeing another leading lady – Charlize Theron. In May, however, PEOPLE's reigning Sexiest Man Alive said he wasn't ready to move on.

"I'm not out of it yet," he said of the inevitable pain that comes with a breakup.

Johansson, 26, has already weathered another breakup. Last month, the actress ended things with Sean Penn after a whirlwind romance that started in March.
