Right now, you can watch the video for "ME!" below, with the audio-only version available at the bottom of the page.
The song marks Swift's first new song since the release of Reputation in 2017.
For the single's actual artwork, Swift has ditched the snake imagery and black, studded clothing of that era, opting instead for a new motif of pastel-coloured flowers, butterflies, hearts and sparkles.
Earlier today, she unveiled a mural in Nashville revealing the new song's title.

Earlier tonight, she also appeared on ABC's NFL draft coverage to talk about the song, describing it as a song about "embracing your individuality and really celebrating it and owning it."

With a pop song, we have the ability to get a melody stuck in people's heads and I just want it to be one that makes them feel better about themselves."
