Many of the performers for the Grammy Awards have already been announced, however, there are still a few vacant spots that are leaving question marks.

According to Billboard, Beyonce will be paying a tribute during the "Selma" telecast, but it is yet to be confirmed. Common and John Legend, who are behind "Glory," the Oscar-nominated song from "Selma" on the other hand, have already been announced and confirmed as performers.

Other performers include Rihanna, Kanye West, and Paul McCartney, who will be at the awards ceremony for the "world debut performance" of their single, "FourFiveSeconds."

The Guardian noted that the single was released only over a week ago, posted online just last Tuesday. The look for the video, according to Rihanna, was the "street denim, all-American-type look" that was Kanye's idea. She shared, "It's iconic, like the f***ing Beatles."

The trio will be joining a plethora of other talented artists, among which are Ed Sheeran, Madonna, and Sam Smith. One crowd favorite artist, however, will not be performing onstage.

Despite 2014 belonging to Taylor Swift - according to the New York Daily News, she became the top-selling artist of the year for her album "1989," and withdrawing her music from streaming service Spotify made her a hero in the music industry - the 25-year-old country-turned-pop-star said that she will not be performing at the prestigious awards show.

Don't panic just yet, she is still going! Swift said on her Tumblr blog, "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."

She later explained that she's focusing on the preparations for her "1989 World Tour," adding, "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!"

As noted by the Music Times, the 57^th Annual Grammy Awards will air live from the Los Angeles Staples Center on February 8 at 8PM on CBS, with rapper LL Cool J hosting the biggest event in music.

Who are your bets this year?
