Hilary Duff’s husband Matthew Koma selling anti-Kanye West shirts

No mercy.

Hilary Duff’s husband, Matthew Koma, has a clear and concise response to Kanye West’s recent antisemitic behavior: “F–k Ye.”

The singer-songwriter, 37, took to Instagram on Monday to reveal that he is selling T-shirts with the message emblazoned in giant capitalized black letters.

The shirts allude to Nazi swastika tees that 47-year-old West, who goes by “Ye,” recently began selling on his Yeezy.com website before being shut down by the hosting platform Shopify on Tuesday.

“Hey I can make a shirt too – link in bio,” Koma captioned a pic of the tee.

After commenters suggested he donate the sales proceeds to a nonprofit benefitting holocaust victims, Koma quickly embraced the idea.

“Thank you for the charity suggestions 🧡,” he replied on Tuesday. “All proceeds going to the Blue Card holocaust survivor charity.”

Koma also updated the post’s main caption to mention the Blue Card organization.

Ye bought a Super Bowl ad that aired on Sunday to promote the now-shuttered storefront, which was only selling the $20 swastika tee. According to TMZ, the “Gold Digger” rapper sold 10,000 units, earning him $2 million against the reported $8 million he spent for the 30-second commercial.

The tee’s online listing was labeled “HH-01,” code for “Heil Hitler.”

In its statement released Tuesday, Shopify explained that they shut down Kanye’s site because it violated the E-commerce platform’s terms of service.

“All merchants are responsible for following the rules of our platform. This merchant did not engage in authentic commerce practices and violated our terms, so we removed them from Shopify,” it said in a statement.

Speaking with CNBC, Shopify President Harley Finkelstein said the owners of Yeezy.com “had an entire day” to prove they were not violating company policies, “which did not happen.”

“The moment we realized this was not actually a real commerce practice, they weren’t actually engaging in authentic commerce, we pulled it down,” the exec told CNBC’s Sara Eisen.

Calling Ye’s website “disappointing,” Finkelstein added, “I’m a proud Jewish entrepreneur. I’m a proud Jewish community member. You and I have talked about this in the past, that it’s a big part of my identity. So obviously I’m devastated by that.”

Ye has been on an antisemitic tirade as of late, calling himself a Nazi and declaring his love for Adolf Hitler in posts on X.

“Hitler was sooooo fresh,” the rapper wrote in one post.

“I’m a Nazi,” he said in another. “I love Hitler.”

His account has since been deactivated.

The rapper has also been dropped by his music booking agent, Daniel McCartney of 33 & West, following his antisemitic comments.

A representative for Ye did not immediately respond to The Post’s request for comment.
