She's never been so excited to be paired with another human being in her life. He went to about 5 shows in a row in plain sight, played in Phoebe's band opening for several of them, they did that weird thing where they mouthed love messages to each other on their respective tours... I said this last week so I'm sorry if I'm a broken record but she's openly encouraging being linked with him even if its just friendship or professional.I'm not responsible for anything my partner says, neither is she.
She's also chronically online and aware of her public image, its part of what makes her a genius. She knows what Matty said, its just a question of whether she doesn't care or is ignoring it and hoping it will go away. In either case its a terrible look.
There's plenty of things even to this day that Taylor deserves to be defended over and there are double standards littered all over her history as a public figure, and many of them still stand. But she doesn't need to be defended over this. I don't think it will kill her career or even dent her momentum much, but its a terrible look.
