While the 'Shake It Off' singer will be having a 'dance party/rage fest' in the audience, she won't be performing.

Get ready to be super disappointed: Taylor Swift won't be performing at the GRAMMYs on Sunday.

While everyone was hoping to see another performance as good as her debut of "Blank Space" at the American Music Awards in November, the "Shake it Off" singer revealed that she simply doesn't have time to get something ready for the show due to preparing for her upcoming 1989 World Tour.

Taylor wrote on Tumblr, "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."

Which means we won't be getting to see any of Taylor's hilarious "crazy faces" that made the AMAs so much fun.

She only has a few months before the 1989 World Tour begins in Japan on May 5, 2015.

At least the 25-year-old megastar is still going to be having a great time in the crowd.

"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," Taylor said in her post. "I will also be presenting the award for Best New Artist."

Unfortunately, it looks like that won’t be happening any time soon, as Perry subtly confirmed that they are feuding. Check out the video below for more!
