Pro tip: Matthew Koma is married to Hilary Duff — not Hilary Swank.
The music producer had a hilarious response to fans mistakenly congratulating him after the “Million Dollar Baby” star gave birth to twins.
“Really appreciate the congratulatory messages today guys. Thank you,” Koma wrote on his Instagram Story Monday.
“@hilaryswank and I couldn’t be happier,” he jokingly added.
The DJ, 35, also included a screenshot of one of the direct messages he received.
“Congrats!” a social media user wrote. “That makes 5 children.”
Koma posted his sarcastic upload one day after Swank, 48, debuted her infant son and daughter via Instagram.
“It wasn’t easy,” the “Alaska Daily” star wrote Sunday. “But boy (and girl!) was it worth it. Happy Easter! 🐣🐣 Posting from pure Heaven. 🙌🏽.”
Swank shares her little ones with her husband, Philip Schneider, whom she married in August 2018.

As for Koma, the singer welcomed daughters Banks, 4, and Mae, 2, with Duff, 35, in October 2018 and March 2021, respectively.
He is also the stepfather to the “Lizzie McGuire” alum’s 11-year-old son, Luca, from her previous marriage to Mike Comrie.
Koma and Duff have been married since December 2019, and he often roasts his wife on social media.
The “How I Met Your Father” star called her hubby her “own personal troll” in a January tribute, writing, “You tease and give me hell Matthew and I love you so much.”
Koma has also made headlines for trolling other A-listers over the years, from Candace Cameron Bure to Gwyneth Paltrow.
In July 2022, the songwriter called out the “Full House” star after she posted a Fourth of July video set to “Born in the U.S.A.,” explaining that the lyrics are “about veterans coming home from Vietnam and being treated like s–t.”
Cameron Bure did not respond at the time — and neither did Paltrow when Koma’s Twitter account was suspended earlier this month after he impersonated the Goop founder.
He joked via Instagram that “closure [was] hard,” thanking Paltrow for the “inspiration.”
