But don't fret! The superstar did reveal that we'll all still get to experience some of her signature dance moves—they'll just be taking place in the audience. In a post on her Tumblr account yesterday, Swift explained the reason why we won't see her "Shake It Off" onstage:
A lot of you have been asking about the Grammys this week and I just wanted to give you an update. I’m really excited to be nominated for 3 Grammys this year and even more excited that I’ll be there having a dance party/rage fest in the audience. I will also be presenting the award for Best New Artist. Since my whole life is wrapped up and entangled in the planning of The 1989 World Tour right now, I’m not going to be performing on the Grammys this year. I need this time to focus only on the tour.
I hope I’ll see you out there at one of the stadiums this summer having a rage fest of your own!
While we're thrilled that Swift is working hard to make The 1989 World Tour amazing (there's no bad blood here), when it comes to giving a performance at the Grammys, we wish you would, Taylor, we wish you would.
Tune in to the 2015 Grammy Awards this Sunday, Feb. 8, at 8 p.m. ET on CBS.
