Kourtney Kardashian and Travis Barker are packing on the PDA in Italy!

On Sunday morning, the couple posted a pair of steamy photographs documenting their latest trip together.

In a post shared by Kardashian, 42, the pair are seen sharing a kiss during a romantic boat ride. For the snapshot, the Keeping Up with the Kardashians alum wore a black thong bikini as Barker, 45, opted for a pair of matching swim trunks with his plethora of tattoos on full display.

"That's Amore," Kardashian captioned the sultry snap, as Barker commented on the post with a simple black heart emoji.

In another post shared by Barker, the couple share another smooch on a boat. "Italy 🖤," the Blink-182 drummer captioned the affectionate snap.

The pair's romantic trip to Italy comes less than a month after Barker flew on a plane for the first time since his deadly 2008 plane crash, which killed 4 people and left Barker with third-degree burns on more than half of his body.

"It's a huge deal that Travis flew to Cabo. The plane crash many years ago was extremely traumatizing. He has needed a lot of help to get to this point," a source told PEOPLE at the time. "Kourtney has been very supportive. She never pushed for him to fly. They have managed to travel in the US without having to fly and Kourtney has been totally fine with it."

Barker even documented the event on Instagram, posting a photo of himself holding up and kissing Kardashian in front of the jet. "With you anything is possible," Barker captioned the post, which Kardashian later shared to her Instagram Story, adding, "anything and everything with you."

In January, a source confirmed Barker and Kardashian's relationship to PEOPLE, and the couple made things Instagram official over Valentine's Day weekend.

Since then, their romance has continued to heat up. From Barker tattooing Kardashian's first name on his chest to the pair packing on the PDA during a romantic trip to Utah earlier this year, the pair haven't shied away from showering one another with affection.
