Irina Shayk and Michele Morrone are heating up the streets of Napoli, Italy.

The supermodel and the actor were snapped enthusiastically making out in public in photos obtained by Page Six.

But the steamy makeout session was strictly professional — the two were shooting a Dolce & Gabbana ad campaign together.

Shayk, 39, embraced Morrone, 34, as they shared a passionate kiss. These attractive stars quickly separated when the cameras paused, exchanging laughs between takes.

The “365 Days” star looked handsome in a gray suit while Shayk showed off her toned figure in a sheer black top and skirt.

The two have both starred in multiple Dolce & Gabbana campaigns separately, though never together until now.

Morrone has shown clear chemistry with his co-actors before. Last December, his representative clarified that he wasn’t romantically involved with his “Subservience” co-star Megan Fox following a playful video featuring the two.

The Italian actor also stood up for his “A Simple Favor 2” co-star Blake Lively that same month amid her legal battle with Justin Baldoni.

“I don’t usually make this kind of video, but I feel it’s important to support someone I truly adore, and that person is Blake Lively,” he mentioned in a video on his Instagram Stories.

Morrone said the two got a chance to talk after he felt her “pain” and sensed that “something was wrong” while filming.

“Blake was in pain. And I’m really tired to see those kind of cruel and bad comments about her without knowing the situation,” he continued.

Morrone is currently single.

As for Shayk, a source told Page Six in February that she briefly rekindled her casual romance with Tom Brady more than year after their initial fling fizzled out.
