Fans think that Taylor Swift and her boyfriend for three years, Joe Alwyn, might be already engaged. The lyrics of her upcoming single "Lover" sparks rumors, with most fans speculating the couple's engagement and ready to tie the knot.

Swift has been through several relationships over the past years, and some deemed the 29-year-old singer as unlucky in love. But, ever since she started dating Alwyn, the singer's life has changed. While she's been open with her previous romance, Swift becomes super quiet about her relationship with the English actor. That's also one of the reasons why fans think he is the one for Swift.

The singer has, constantly, been dropping hints about her life and music through her songs, and Swifties think "Lover" has a secret message. Recently, engagement rumors involving the couple has emerged after Swift shared some lyrics of her upcoming album, which is set to launch this August 24 - in the cover story of Vogue magazine's September issue.

According to Vogue writer Abby Aguirre, the track is a singer-songwritery nugget, waltzy, haunting, and romantic. The singer also revealed that the song is co-produced by Jack Antonoff and it features one of her favorite bridges.

"My heart's been borrowed, and yours has been blue. All's well that ends well to end up with you," Swift sings "Lover." This prompted fans to believe t that the song probably has a hidden meaning - possibly engaged to Alwyn.

Swift's fans immediately went on Tumblr - a microblogging site the singer used the most - and shared what they felt about the song and discussed the meaning of it. The singer liked a particular post of a fan, which fuelled the rumor that she might be engaged with the 28-year-old actor.

Now, several social media users have claimed Swift confirmed her engagement through the song, though she hasn't commented about the speculation - neither has her boyfriend. As of late, the singer hasn't also been spotted wearing an engagement ring.

Still, most of her fans are convinced the lyrics of "Lover" hints Swift and Alwyn are already talking about marriage. Ever since they started dating, rumors have been tailing them and claimed the actor was the one for the singer. Perhaps, the engagement rumors might be addressed once the new album drops later this month.

In May 2017, Swift and Alwyn first revealed their romance to the world, but the couple reportedly started dating month prior - or as early as September 2016. The singer has stepped back from the spotlight in 2016 and 2017, and she made an active choice to keep her relationship private and close to her heart.
