But perhaps the biggest confirmation that there's something going on between Taylor and the British indie rocker is Matt's recent interview with Shazam Top 20, when he admitted that there was potential for a relationship between the two.
"I met Taylor Swift, that was really nice," he said. "We exchanged numbers. Let’s see what happens. I mean what am I going to do? Go out with Taylor Swift? She's a sensation. I wouldn't say no."
And they're certainly not being shy about their mutual admiration for one another. Healy wore a "1989" shirt in November, and Taylor was also spotted out and about in a 1975 muscle tee last month.
According to some fans at Thursday night's NYC show, Healy even pointed at Taylor while singing his song, "Falling For You."
