Mayor Jacob Frey tells us he and the rest of the city are ready to welcome TayTay with open arms this Sunday, which is when the Kansas City Chiefs play the Minnesota Vikings for an afternoon match-up -- he even has an on-the-nose message to encourage her.

Frey says, "We know All Too Well the positive impact Taylor Swift has on the cities she visits -- Minneapolis is no exception."

The Mayor has fond memories of her tour stop in Minneapolis earlier this year, adding ... "Her two, sold-out concerts at U.S. Bank Stadium in June led to a record-setting tourism weekend including booked-up hotels and packed downtown restaurants... boosting our local economy beyond our Wildest Dreams."

Here's how you know Mayor Frey has his fingers crossed ... "If Taylor chooses to come back to Minneapolis [sometimes known as Swiftieapolis] this weekend, we’ll be Ready For It. It’s possible she will have to console Travis Kelce after the Vikings beat the Chiefs, but there are plenty of great spots across town for them to go on a date and lift their spirits!"

FWIW, the Swiftieapolis thing is real ... they literally changed city's name (if only for a short time), so yeah -- with his clear knowledge of Taylor's catalog -- it's fair to say Hizzoner's a full on Swiftie.

Fact is, every NFL city would feel this way ... as Taylor's proven to have massive appeal in terms of media attention, and consumer spending across multiple industries, that usually translates to more traffic ... and oftentimes, more moolah, too.

The 2 NFL games she's attended have turned out to be a ratings bonanza for Fox and NBC, the networks that televised them. Next week, it's CBS's turn and it sounds like Mayor Frey wants to get in on the action as well.
