Justin Timberlake acceptance speech

While accepting his award for song of the year, Timberlake delivered an inspirational and inclusive speech directed at young people. The former N*Sync singer said of Can't Stop The Feeling: "I wrote this song because I wanted it to be about inclusion, about being together. I want to take this opportunity to speak to young people right now – because there's a lot of you looking at me.

"If you are black or you are brown or you are gay or you are lesbian or you are trans, or maybe you're just a sissy singing boy from Tennessee. Anyone that is treating you unkindly, it's only because they are afraid or they have been taught to be afraid of how important you are. Because being different means you make the difference, so f**k 'em."

DJ Khaled's son steals the spotlight

It was a star-studded audience but one little fella stole the show. DJ Khaled brought his four-month-old son, Asahd, along as his special guest for the ceremony.
