So far, the two have been low-key about their relationship, although Renee, 30, has confirmed she's pregnant on social media.

"I am VERY pregnant, by a pool, in Vegas," she tweeted last month, linking to an Instagram snap of her sporting a bikini and sunglasses.

In April, Zano sweetly Instagrammed a pic of the Grimm actress, calling her his "Woman Crush Wednesday."

A visibly pregnant Renee and Zano were "very affectionate" toward each other during a dinner date at Laurel Tavern restaurant in Studio City, California, on Wednesday, an eyewitness tells ET.

"Nick and Leah were kissing and holding hands at one point," the eyewitness notes. "It was just the two of them. They kept to themselves and seemed very happy together."

The last public appearance the couple made together was in late January, when they attended the DEN Meditation Studio grand opening in Los Angeles. Renee wore a loose white top under a leather jacket, possibly covering up her growing baby bump.
