Just days before he was spotted with his arm around Rumer Willis, Armie Hammer went on a date with Jessica Ciencin Henriquez, Page Six has learned.

A source confirmed that the “Call Me by Your Name” star dined with Henriquez, who is the ex-wife of actor Josh Lucas, at West Hollywood restaurant Mamma Osteria last Monday. We’re told the lunch was their first date.

Henriquez, 34, played down the meal as romantic, later telling Page Six, “That’s just me having lunch.”

But when asked how long she and Hammer had been dating, Henriquez had no comment.

A rep for Hammer, 34, didn’t return Page Six’s request for comment.

Writer Henriquez filed for divorce from Lucas, 49, in January 2014 after nearly two years of marriage. The exes appeared to have reconciled in some capacity at some point, as Henriquez accused the “Sweet Home Alabama” star of cheating on her during quarantine.

“But it takes a really s–t human to cheat on their partner (correction: now ex partner) in the middle of a pandemic,” Henriquez shared on social media in May.

“Thank you for reminding me why I left you in the first place. I deserve better than this. Our son deserves better than this.”

She and Lucas are the parents of 8-year-old son Noah.

Meanwhile, Hammer and wife Elizabeth Chambers, announced in July they were separating. Chambers, 38, filed for divorce from Hammer days after the joint announcement. She cited irreconcilable differences as the cause of the split.

Hammer and Chambers share two children, 5-year-old daughter Harper and 3-year-old son Ford.
