To explain that, we have to go all the way back to 2011, when Taylor and Dianna were very close friends and actually rumored to be dating at one point.

The rumors are just that, and they are completely unverified and just a fan theory.

However, fans are still convinced that something happened between Taylor and Dianna.

During her performance, Taylor explained to the crowd that while writing “Wonderland”, she “based it off of a twisted Alice in Wonderland”.

Swifties made the connection and instantly thought of Dianna, who, actually had a tattoo of a quote from the Lewis Carroll tale on the side of her torso.

After “Wonderland” first debuted, Dianna had it removed.

Fans also have theories about this other song of Taylor‘s possibly referencing her relationship with Dianna.

You can watch a video of Taylor performing “Wonderland” on Twitter.

Earlier this month, the official set list for Taylor‘s Eras Tour was revealed.
