They’re oldies but Swifties.
Seventy-something Taylor Swift fanatics are not shy when it comes to expressing their devotion to the pop star, and are buying her music, seeing her movie, and joining her fan groups — while their friends are off playing shuffleboard.
Great-grandmother Linda Fox, 74, said she refrains from speaking about Swift with people her age.
“I don’t really talk to my friends about it … I’m trying to stay younger,” she told The Post.
“I just hang out with the teenage girls. They call me ‘Swiftie mom.’”
Fox became a Swift fan because of her 16-year-old granddaughter, Phoenixx Brito.
Brito’s house burned down on Christmas night last year, so she lived with Fox, who tried to make new Swift memories for her since all of her memorabilia was destroyed.
“Everything that we bought her for Christmas, the albums, the sweatshirts were still under the tree,” Fox said. “She was so heartbroken. So I went out and got a little record player.”
The duo spent time listening to Swift’s music together.
“We used to lay here… And Taylor Swift got her through it.”
In June, Fox, a Yardley, Pa., resident, and her daughter drove Brito and her friend to Swift’s concert in Pittsburgh.
The tickets for the show were over $2,000 each, so Fox and her daughter couldn’t attend.
“I’m on social security and a pension and I can’t afford those tickets,” she said, laughing.
Fox, who has four children, eight grandchildren, and two great-grandkids, also took Brito and her three friends to Swift’s concert movie, “Taylor Swift: The Eras Tour” and even crafted a cowboy hat to wear for the occasion.
Roger Stock, 74, grew up listening to the Doors, Cream, Jefferson Airplane, and the Grateful Dead — and is now a member of two Swift Facebook fan groups.
A native of Wales who now lives in Cyprus, Stock began listening to Swift’s music in 2011 after he realized “she wrote almost a perfect story in the lines of a song” with “I Knew You Were Trouble.”
When her album “Red” was released in 2012 and he heard “All Too Well,” the ballad Swift penned based on her short-lived relationship with Jake Gyllenhaal, he was hooked.
“I bought ‘Red’ on CD and when she released her catalog on Spotify, I was well pleased,” Stock said.
His wife is “not really” a Swiftie, and sometimes pokes fun at him.
“I am now getting more ribbing off her because of the increased coverage Taylor Swift gets now,” he said.
His son is not a fan either, but “respects” his father’s musical choices. “I trained him well,” Stock said.
Sandy Bevil, 71, from Charlotte, N.C., is a proud member of six Swift fan Facebook groups — and is such a loyal devotee that she went to Swift’s movie by herself because she doesn’t have any friends who are fans.
“I had to go see the movie alone. I got a couple of young girls to take a picture of me in front of the poster while I was there to prove that I had been,” she explained.
Bevil is also a football fan and said her favorite team is “the Chiefs, who else?” — since Swift is dating its tight end Travis Kelce.
