Taylor Swift Announces New Song 'You Need to Calm Down' & 'Lover' Album Release Date

"You Need to Calm Down" arrives at midnight, with a video out Monday, while her seventh album drops on Aug. 23.

We knew there was new Taylor Swift music on the way, and now we know when to expect it.

On Thursday (June 13), Swift went live on Instagram to tell fans that a brand-new song called "You Need to Calm Down" comes out at midnight ET, with a video to follow Monday on Good Morning America ("The video is very worth the wait," Swift promises). In addition to the new song, Swift also revealed the name, cover and release date for her much-anticipated seventh album: Lover will arrive on Aug. 23.

The 18-track album is "very romantic," Swift told the hundreds of thousands of fans who tuned in to her Instagram Live -- but don't expect all love songs. "Not just simply thematically. … You can find romance in loneliness or sadness."

In addition to the standard physical CD, there will also be four deluxe editions of Lover available via Target. Each of the four deluxe editions will include different content, Swift said.

But wait, there's more! Swift also revealed a collaboration with designer Stella McCartney, who will release fashions inspired by the music of Lover.

Swift thanked her fans for their detective skills in combing through all her newest releases for hints -- including lead single "ME!" and its clue-filled music video. "I've been so, so, so honored to your dedication to discovering easter eggs," she said. She dropped a new egg for fans too: If you break down that Aug. 23 release date, 8 (August) + 2 + 3 = 13 -- Swift's famous favorite number.

So stay tuned for more clues and more music, as the Lover era officially starts now.
