Swift, 25, announced the '1989 World Tour' in November last year. The singer said she needs time to plan the tour, hence will not perform at the event, set to take place on Sunday, February 8, reported E! Online.
"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," she shared on Tumblr yesterday.
