The 57th Annual Grammy Awards aired live tonight on CBS from Los Angeles' Staples Center and included big wins for LGBT artists and some great performances!

Out British singer Sam Smith made history tonight as the first openly gay winner of the Grammy Award for Best Pop Vocal Album. It was one of four wins for Smith who also took home Grammys in Best New Artist, Song of the Year and Record of the Year for "Stay With Me (Darkchild Version)." "It was only until I started to be myself that the music started to flow and people started to listen," Smith said. "Just a quick one, I want to thank the man who this record is about who I fell in love with last year. Thank you so much for breaking my heart, because you got me four Grammys."

A Great Big World, which includes out singer/songwriter Chad Vaccarino, picked up a win in Best Pop Duo/Group Performance for their song "Say Something" with Christina Aguilera.
