Nashville, Tennessee - To say Taylor Swift's weekend in Nashville for The Eras Tour has been eventful would be an understatement, and eagle-eyed fans are raising questions about The 1975 frontman Matty Healy's role in the musical madness.

From announcing the release date for Speak Now (Taylor's Version) to allowing boygenius to take the stage alongside member Phoebe Bridgers' opener slot on Friday night, The Eras Tour stops in Nashville have been epic, to say the least.

Then, you add Matty Healy, lead singer of The 1975 and Swift's alleged new boo after her rumored split from longtime boyfriend Joe Alwyn, into The Eras Tour mix, and what many Swifties are left with is a handful of questions.

Fans were quick to scope Healy out in the VIP tent at Nissan Stadium on Friday night, and though he kept a decently low profile, it didn't stop social media users from running rampant with theories as to why he was in attendance.

Flash forward to Saturday night, and Healy was nonchalantly spotted on-stage alongside Bridgers during her opening set.

As if the 34-year-old musician's presence at Swift's Nashville shows wasn't enough to send a select group of diehard Swifties into a tailspin, some think the pair are sending each other secret messages during their respective shows recently.

On May 3, The 1975 played a show in the Philippines, and Matty was seen mouthing "this is about you, you know who you are. I love you," to the camera before taking a sip out of a bottle of wine, seemingly sending someone a secret love message.

Then, at Swift's The Eras Tour show in Nashville two days later, the 33-year-old Question...? artist was filmed mouthing the same words during her performance of the Folklore track, Cardigan.

Since Healy was in attendance, it's not far off to assume Swift may have been sending her rumored new man a message.

Or perhaps both Healy and Swift are clowning their respective fanbases in shameless style – only time will tell!
