Jake and Taylor dated back in 2010, and many have speculated for years that her song "All Too Well" is about the "Nightcrawler" actor, although that's never been confirmed.
On Sept. 28, though, Jake posted a throwback photo in which he wears glasses.
"I've worn my glasses ever since I parted my hair meticulously with gel (see above), which is why NEW EYES has always been near and dear to my heart," he captioned that photo, which was shared to promote New Eyes for the Needy, an organization that provides prescription eyewear to those in financial need.
The organization recently partnered with The Inspire Project, as well.
While the cause is certainly noble, the message may have gotten lost in comments section. Swifties pounced on Jake the moment the picture was posted, with a slew of them referring to line in "All Too Well" which says, "You used to be a little kid with glasses in a twin-sized bed."
One fan quickly replied, "Give taylor swift her scarf back." Another said, "u posted this pic and thought that the swifties would do nothing???? mistake."
A fan joked, "Reminds me of this song I know."
Many fans began asking Jake other questions linked to the song. "Were you on a tee-ball team too?" one fan trolled. Another said Jake was "talking about his past thinking the future," another reference to the song.
Swifties never take a day off.
