After Taylor Swift, 30, unveiled her newest album “Folklore” early Friday, it wasn’t long before superfans started circulating a theory that the song “Betty” is in fact named after Ryan Reynolds and Blake Lively’s youngest daughter. Swift has long been friends with the acting power couple.

Swift’s fans, or “Swifties” as they’re often called, noticed that since Reynolds, 43, and Lively, 32, announced the birth of their daughter on Oct. 4, the actors never released the name of their now 9-month-old girl.

The dots started to connect when sleuths noticed that Swift used the names of the couple’s other children, 3-year-old Inez and 5-year-old James, in the song’s lyrics.

“Betty, I know where it all went wrong,” Swift sings. “You heard the rumors from Inez. You can’t believe a word she says . . . James, get in, let’s drive.”

Naturally, fans believe the name Betty must be referring to Lively and Reynolds’ third child. The revelation could be one of many Easter eggs the songstress famously drops in her songs.

“Anyone else pick up on @taylorswift13 using James and Inez as character names in ‘Betty’? @VancityReynolds and @blakelively’s daughters’ names! Now I want to know their third daughter’s name — is it Betty?! #TaylorSwift #Folklore #TaylorSwiftFolklore @taylornation13,” one person tweeted.

Another echoed the sentiment.

“I need to know if Betty is @blakelively and @VancityReynolds 3rd child,” one fan tweeted. “It can’t be a coincidence that James and Inez are lyrics in the same song. I love Blake and I need to know @taylorswift13.”

The conspiracy has yet to be confirmed, and reps for Reynolds and Lively didn’t return The Post’s request for comment.

If proven true, this wouldn’t be the first time James made an appearance on a Swift track — she was credited in the singer-songwriter’s 2018 tune “Gorgeous” as the intro voice.

Fans were floored Friday morning after Swift dropped her eighth studio album, “Folklore,” with very little warning, save for a teaser on Thursday.

Comprised of 16 tracks, the compilation comes less than a year after her peppier disc “Lover” was released in August of last year.

Her latest musical feat is a stark contrast to her previous works, focusing on more lo-fi production and a downbeat tone. It’s not a surprise as the singer admits she composed the tunes during quarantine.

Other song titles include “Illicit Affairs,” “Mad Woman,” “The Last Great American Dynasty” and “Cardigan.”
