“Oh hey there,” Barker captioned the post, pulling up his black checkered boxers to show off the new ink in a full-length mirror selfie.
A close-up of the design shows an uncanny likeness to Kardashian, 43, which she shared on her own Insta Story with a GIF of blinking eyes.
The post also included a photo of Kardashian posing for a selfie in the same bathroom mirror, as Barker hides behind her on his knees with his hands on her thighs.
Yet another shot showed a profile of Barker with his Alpha Industries bomber jacket hanging off his shoulder, standing in front of a mural and art installation featuring a boom box.
Kardashian has previously revealed her favorite tattoos Barker has gotten in tribute to her. “The Kourtney, of course,” she said on TODAY, referring to the tattoo on his chest. She noted that she’s also “tattooed him” herself.
Barker also referred to the “I love you” ink from Kardashian as “my favorite tattoo from my favorite tattoo artist.” He shared a photo of it on his Instagram Story in 2021 after the Poosh founder completed her masterpiece earlier that year.
