The nominations for the 2015 Grammy Awards are rolling in and Pharrell Williams, Sia and Sam Smith are already racking up quite a few. All three artists are competing against each other in the best pop solo performance category for "Happy," "Chandelier" and "Stay With Me," respectively.

Smith was also nominated for best pop vocal album, record of the year and best new artist. Williams is up against Beyoncé and Chris Brown, among others, for best urban contemporary album.  

This year the recording academy is doing things a little different and won't announce the nominations all at once. Instead, the noms are being revealed on Twitter first as the artists share the good news with their fans.

Breakout YouTube star and singer Troye Sivan tweeted that he had some important Grammy news to share with his fans.

"YO dudes I'm posting something soon that I can't believe I'm actually posting," he wrote.

HNGN will be updating the nominations list as the news is announced so be sure to continue checking back. Nominations for album of the year will be announced later tonight on CBS during "A Very Grammy Christmas."
