Taylor Swift took to Good Morning America on Wednesday (July 31) to announce a special once-in-a-lifetime concert.

Fans were shocked to see a surprise promotional video of Swift during The Bachelorette finale last night (July 30) where she said that she had a big announcement to make on Good Morning America the next day.

That big surprise was the announcement of a Good Morning America concert in New York City's Central Park. The show will take place on August 22, the day before her seventh studio album, Lover, debuts.

Swift previously performed a concert on GMA on the release day of her fifth studio album, 1989.

At this time, there are no details for fans wanting to see the performance in-person. Previous GMA concerts have been on a first come, first serve basis and through a lottery ticket process, depending on the concert. Fans can visit Central Park's website for the most up to date information.

Four deluxe editions of Lover will be available at Target on August 23. Each edition will feature pages of Swift's diaries through the years along with two audio tracks where fans can learn how she creates a song.
