Kardashian, who turned 42 on April 18, has been keeping fans up to date on the dreamy vacation by a sharing snapshot of the trip on Instagram.
“Just Like Heaven,” wrote the reality TV star, while captioning a photograph of her new boyfriend holding her legs around his waste during a passionate kiss.
The Blink-182 drummer previously posted an adorable birthday tribute celebrating Kardashian’s special day.
“I F***ING LOVE YOU!” he wrote in the caption. “YOU’RE A BLESSING TO THIS WORLD…HAPPY BIRTHDAY @kourtneykardash.”
Back in March, a source opened up to ET about the couple’s blossoming romance.
“The relationship was a long time coming because the attraction has always been there on both sides,” the source said at the time. “They love the fact that they have a true friendship and bonded that way before taking anything further and making things romantic.”
