Grammy Awards 2015 nominations announced

Ed Sheeran and Pharrell Williams kicked off the 57th annual Grammy Awards nominations by unveiling contenders in four categories on "CBS This Morning" on Friday. Both acts heard their names called, too. Sheeran peaked at the ballot before he heard his name -- so he wasn't too surprised upon hearing it, but seemed happy nonetheless.

It was an early start for Sheeran and Williams, who were on the West Coast to announce the nominations.

Sheeran, who's up for best pop vocal album, took to Twitter after the appearance:

Grammy nom and my album multiply has sold 3 million worldwide as of this morning. Good start to the day, thanks for all the support and love

— Ed Sheeran (@edsheeran) December 5, 2014

Between 9 a.m. and 2 p.m. ET more categories will be announced via Twitter, with various celebrities doing the unveiling throughout the day.

Nominees for the biggest Grammy category, album of the year, will be announced on "A Very Grammy Christmas," set to air at 9 p.m. ET on CBS. The holiday special will feature performances by some previous Grammy winners and potential 2015 Grammy nominees, including Sam Smith, Ariana Grande, Big Sean, Mary J. Blige, Maroon5, Williams and Tim McGraw.

Former Grammys host LL Cool J will emcee the one-hour special. The Grammys really do love LL -- he's hosted the ceremony the last two years.

Winners for the 2015 Grammy Awards will be announced Feb. 8 on CBS.
