Taylor Swift is opening up about her own "Love Story."

The "Cardigan" singer, who has kept her relationship with actor boyfriend Joe Alwyn mostly private, tells Beatles legend Paul McCartney her 2020 song "Peace" "is actually more rooted in my personal life." Swift and McCartney's in-depth talk is featured in Friday's "Rolling Stone" cover story.

"I know you have done a really excellent job of this in your personal life: carving out a human life within a public life, and how scary that can be when you do fall in love and you meet someone, especially if you’ve met someone who has a very grounded, normal way of living," Swift told McCartney.

"I, oftentimes, in my anxieties, can control how I am as a person and how normal I act and rationalize things, but I cannot control if there are 20 photographers outside in the bushes and what they do and if they follow our car and if they interrupt our lives. I can’t control if there’s going to be a fake weird headline about us in the news tomorrow."

When McCartney inquired whether her partner could "sympathize with that and understand," Swift responded in the affirmative: "Oh, absolutely."

"I think that in knowing him and being in the relationship I am in now, I have definitely made decisions that have made my life feel more like a real life and less like just a storyline to be commented on in tabloids," she explained.

Fans learned Swift was dating Alwyn in May 2017, though the pair kept things under the radar for months.

Swift's hit 2017 album "Reputation" included several tracks hinting at their love story – including "Gorgeous," a song that has the pop star waxing poetic over her beau's "ocean blue eyes." Her 2019 album "Lover" is even less subtle, with a song titled "London Boy," about being in love with a man from across the pond. 

Alwyn has stayed pretty tight-lipped about Swift. “I’m aware people want to know about that side of things,” he told British Vogue in Sept. 2018. “I think we have been successfully very private, and that has now sunk in for people ... I really prefer to talk about work.”
