All signs are pointing towards Matty Healy and Taylor Swift bein' more than just a couple of singers ... because The 1975 frontman took in all 3 of her shows over the weekend, making fans more and more convinced the 2 are an item after all.
Here's the deal ... Matty was spotted once again Sunday at Taylor's Eras Tour concert in Nashville -- grooving along to her hits in a private area with some other folks.
As we reported, he was also seen Friday and Saturday, where one of the nights he put on a seemingly impromptu performance with TS' opener, Phoebe Bridgers -- and even with a group of ladies including Gigi Hadid crowded around him, he's still got all eyes on Taylor.
Of course, this all comes after heavy rumors the 2 are an item ... and if Matty's 3-peat wasn't enough, they were even seen in the same car after Saturday's show, sharing the back seats together. 👀
Some might say he's just one artist supporting another, but come on -- the writing's on the walls!
BTW -- fans at Taylor's Sunday show were met with some serious rainfall at the Nissan Stadium ... but it didn't look like Matt and co. were the least bit bothered by ol' mother nature!
