The Blink-182 drummer, 45, left a sweet note to the Keeping Up with the Kardashians star, 42, on Thursday after the pair took a trip to Disneyland with family.
Posting a picture of himself holding his girlfriend's hand while riding the King Arthur Carousel, Barker wrote in the caption, "Happiest Place On Earth 🌍."
"happiest ❤️," Kardashian responded in the comments section, prompting the musician to reply, "with the love of my life."
According to People.com, in January, a source confirmed Barker and Kardashian's relationship, 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 packing on the PDA during a romantic getaway in Utah, the pair haven't shied away from showering one another with affection.
Earlier this month, Barker got a tattoo of the phrase "I love you" written in Kardashian's handwriting. The unique design was debuted on Kardashian's Instagram.
