Irina Shayk and Michele Morrone have intense public makeout session for steamy-good reason

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, wrapped her arms around Morrone, 34, as they passionately kissed. The good-looking stars abruptly parted as cameras stopped rolling, sharing a laugh in between shots.

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 had obvious chemistry with his co-stars in the past. Last December, his rep denied he was dating his “Subservience” co-star Megan Fox after a flirty video of the two surfaced.

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.

“So it’s usually not my thing to make these types of videos, but I think it’s time to stand up for a person I really love, and this person is Blake Lively,” he said 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.
