This was her 13th Grammy Award, which she said was her "lucky number". She followed this up with an announcement for her new album 'The Tortured Poet's Department', which will be released on April 19.
"I want to say thank you to the fans by telling you a secret that I've been keeping from you for the last two years, which is that my brand new album comes out on April 19."
"It’s called the Tortured Poets Department. I'm gonna go and post the cover right now backstage. Thank you. I love you," she said in her acceptance speech.
Swift is nominated in six categories at this year's ceremony, including best pop vocal album 'Midnights', best pop solo performance 'Anti-Hero', album of the year 'Midnights', best pop duo/group performance 'Karma', song of the year 'Anti-Hero' and record of the year 'Anti-Hero'.
Swift didn't win the award for best pop solo performance. That went to Miley Cyrus' "Flowers" and was her first Grammy.
