In doing so, a mega T-Swizzle fan was unearthed in baben' singer, Charlie Puth.
The "Attention" crooner took to Twitter to share a screenshot from Spotify where he was listening to Tay's early jam, "Our Song".
See, if he was listening to "Shake It Off" or "Blank Space" or even "I Knew You Were Trouble", we'd assume that Puth was a fairweather Taylor fan.
But since he was jamming to her OG banger, it looks like Puth is a die-hard Taylor Swift stan!
Ya hear that Tay? Chuckles is a fan.
