Taylor Swift’s first “From the Vault” song is coming out this weekend. Friday at midnight, “You All Over Me (From the Vault)” featuring Maren Morris on background vocals is the first of six vaulted songs on Taylor’s rerecorded Fearless (Taylor’s Version) album coming out next month.

“One thing I’ve been loving about these From The Vault songs is that they’ve never been heard,” Taylor said when she announced the “You All Over Me” on Twitter, “so I can experiment, play, and even include some of my favorite artists.”

Marren is the first confirmed feature on Fearless (Taylor’s Version), but some Swifties think there might be even more coming. One of those artists might be Taylor’s BFF Selena Gomez. Selena recently posted a throwback photo from Taylor’s Lover era featuring Taylor, Selena, and Taylor’s kitty Benjamin Button. If that wasn’t enough to make both popstars fans excited, Selena’s caption and Taylor’s comment were.

“kinda missin this one” Selena wrote. The caption (not including spaces) is 18 characters. The exact number of days from her post until April 9, which was the date revealed in the secret message from Taylor’s Fearless (Taylor’s Version) note and the album’s release date. Fans also noticed that Selena’s caption is four words while Taylor’s response–“I love u like a love song bay beh 🥰” is nine words. Four. Nine. April 9! Selena could just be supporting her friend by helping her leave clues, but we all know by now that Taylor Swift and coincidences just aren’t really a thing.

We’re excited to see what other experiments Taylor has been working on with her old (and new) music. This Friday, we’ll get our first look!
