We are Her PS Partnerall very excited for Lorde's new song, but don't you dare for a second think that you can match Taylor Swift's enthusiasm.

Swift, of course, congratulated her bestie on the new single "Green Light" with the Apple Music screenshot version of an excited squeal, writing, "g2g brb just gonna make up an interpretive dance to this magnificent bop for the ages."

When a fan pointed out that maybe Swift overdid it a touch, Tay returned to Tumblr -- where the kids are -- to set the record straight. She overdid it, but not as much as she could have.

Maybe Lorde & Tay are really are both hundreds of years old. It would explain a lot.
