Matthew Koma took to Instagram on Monday to show off his new tattoo, which is simply the word “Hilary” on his buttock.

Hilary Duff’s husband has the artist’s name tattooed on his butt.

Matthew Koma took to Instagram on Monday to show off his new ink, which is simply the word “Hilary” written in italics across the lower part of his back.

He wrote alongside the funny image: “Good luck winning a fight with your wife when her name is tattooed on your buttock. #Squats #gainz #laseraway (sic) “

A fan in the comments pointed out that the tattoo design is actually written in Hilary’s own handwriting, as this is how the star signs her name when writing autographs for fans.

And Hilary herself also commented on the post, joking that Matthew is “stuck” with her now that she has his name permanently on her butt.

She wrote: “#youstucknowboy’s finest loot (sic)”

Meanwhile, the 32-year-old actress recently said she is “really grateful” for her spouse amid the coronavirus pandemic, because her new family routine gives her the opportunity to “sleep late” in the morning.

“I am at home all day. So, we came up with this routine in which he lets me sleep late, and does the first three hours with the children in the morning because he knows that once they see me, they only want me’.

“Literally none of my friends say the same thing happens at home. So I am very grateful that he is very involved. So it was great. “
