Minnesota Gov. Tim Walz dropped a not-so-subtle reference to one of Taylor Swift’s songs while taking a swipe at GOP nominee and former President Donald Trump during a campaign rally in Wisconsin on Saturday.

“It’s really great to have all of these women help us beat the smallest man in the world, Donald Trump,” said Vice President Kamala Harris’ running mate in a nod to Swift’s “The Smallest Man Who Ever Lived” from her album “The Tortured Poets Department.”

Walz gave shoutouts to several women including his wife Gwen Walz, three of his sister-in-laws, Sens. Tammy Baldwin (D-Wis.) and Amy Klobuchar (D-Minn.) as well as former Minnesota Rep. Jen Schultz (D) before sharing a “life hack for all the guys” in the crowd.

“Surround yourself with smart women and and listen to ’em and you’ll do just fine,” Walz said. “That includes my fellow cat owner Taylor Swift, too, by the way.”

Walz, who showed off a friendship bracelet as the crowd erupted in applause, previously said he was “grateful” for the pop superstar’s endorsement of Harris when he reacted to the Swift announcement on live TV after Tuesday’s debate.

Swift — an owner of three cats who appeared to spark a surge in visits to a voter information page — called on her fans to register to vote and backed Harris before signing off her post as “Childless Cat Lady.”
