Kourtney Kardashian and Travis Barker are more in love than ever as far as Instagram is concerned; the two are currently enjoying a vacation in Italy, each posting photos of themselves making out on a boat.

Kardashian's post (opens in new tab) shows her in a tiny black bikini with her arms around Barker's neck and her lips firmly on his. She captioned it "That's amore," and he commented with a black heart emoji.

Barker's post, tagged Portofino (opens in new tab), appears to have been taken earlier in the day and shows the two sharing a sweet kiss. He is wearing a spiky black hoodie and she is wearing a plain cover-up with large Prada sunglasses. The caption simply reads "Italy" and is accompanied by a black heart. Kardashian commented, "With you," and added her own black heart.

During their stay in Italy, the two were also spotted walking in Venice. On that occasion, Kardashian wore a black crop top with a short black cardigan and a silky red and black miniskirt, while Barker wore a graphic T-shirt and pinstripe pants.

The couple officially confirmed back in February that they were dating (opens in new tab) and have since shared a fair amount of PDA on Instagram (opens in new tab). Barker also has "Kourtney" tattooed on his chest (opens in new tab), and the two have reportedly been discussing marriage (opens in new tab). Kardashian has three children (Mason, Penelope, and Rain) with ex-girlfriend Scott Disick, but they are not married.
