Two days after the lover's holiday, Kardashian posted a photo of their hands on Insta, with her fingers -- featuring a red hearts manicure -- wound up with Barker's inked-up digits.
She didn't caption the picture, but Barker weighed in with a black heart emoji and then reposted the image to his Insta Story.
According to E! News, the couple began dating in January. Barker has two teenage children from a previous marriage and Kardashian has three children with her ex.
