You know what they say: nothing says "I love you" like getting your partner's name tattooed on your butt. Just ask Hilary Duff [1]'s husband, Matthew Koma, who just revealed that he recently got a tattoo of his wife's first name in a pretty, uh, intimate area of his body. In a hilarious (and NSFW) Instagram photo shared on Sept. 21, the musician showed off his new ink, which is Duff's name written in cursive on his derrière.

"Good luck winning a fight with your wife when her name's tattooed on your butt cheek," Koma captioned a photo of his backside. He, of course, made the picture slightly more Instagram-friendly by adding some peach emoji. And in case you were wondering if the woman in question approves the message, she's definitely appreciative of the honour. "Finest tiniest booty around #youstucknowboy," Duff commented under the photo.

Duff and Koma have been married since December 2019 [2]. The couple tied the knot in an intimate ceremony in Los Angeles seven months after announcing their engagement [3] and just over a year after welcoming their daughter, Banks Violet Bair [4]. Take a look at Koma's "cheeky" new tattoo above.
