Sophie Turner praises Taylor Swift's song 'Mr. Perfectly Fine' which is largely suspected to be about the actress' husband Joe Jonas

• Taylor Swift released her second "from the vault" song on Wednesday, titled "Mr. Perfectly Fine."
• Sophie Turner praised the track on Instagram, writing, "It's not NOT a bop."
• Turner is married to Joe Jonas, who fans suspect inspired the 13-year-old breakup song.

Sophie Turner is a fan of Taylor Swift's newly released song, even though fans think it's a scathing portrait of her own husband, Joe Jonas.

Swift surprise-dropped "Mr. Perfectly Fine" on Wednesday, a so-called "from the vault" song that will be included on her rerecorded version of "Fearless."

As the singer previously explained, the six "vault" songs were written around the 2008 release of her sophomore album, but were excluded from the final tracklist "for different reasons."

"Mr. Perfectly Fine" bears clear similarities to "Forever & Always," another poignant breakup song about "watching somebody completely fade away in a relationship," in Swift's words. It was added to "Fearless" at the final hour, apparently inspired by Swift's then-fresh split from Jonas.

Fan theories and jokes about Swift dragging Jonas flooded the internet upon the song's release - but Turner, who married the Jonas Brother in 2019, isn't phased.

"It's not NOT a bop," she wrote on Instagram.

Swift reposted Turner's reaction on her own Instagram story and praised the "Game of Thrones" actress.

"forever bending the knee for the [queen] of the north," she wrote, referencing Turner's famous role as Sansa Stark.

Swift appears to get along well with the couple, who tied the knot in a surprise Las Vegas ceremony in 2019 after three years of dating.

Turner and Jonas had a second, more traditional wedding several months later and welcomed their first child together in July 2020.

Swift told Ellen DeGeneres that now, she and Jonas can laugh about their messy breakup. She also suggested in her 2020 song "Invisible String" that she sent the couple a present when Turner gave birth.
