Swifties spot major Easter egg that makes Travis Kelce's latest Instagram post with Taylor Swift even sweeter

And here is Swift's: 

That led to plenty of speculation about exactly what outfit she was wearing in the photos and when they were from.

Swift had previously gone Instagram official with Kelce, sharing two photos with the Kansas City Chiefs tight end, both of which were from her Eras Tour concerts in London when she met Prince William and also had Kelce join her on stage. However, this is the first time she's made an appearance like this on his social media page. 

And Kelce certainly delivered in every way. 

But, it didn't stop there. Fans had more theories about it all. 

In one, a Swiftie pointed out how the singer and Kelce were both wearing matching hats, one of which said "captain," while the other said, "first mate." And that related to a merchandise drop Swift had this summer that had a nautical theme. 

Kelce also went Facebook official too! 

We can't get enough of this love story!
