Bruno Mars proved that he may actually be the coolest person to party with when he managed to sneak a flask into the 2016 Grammys. Not only did he live it up for the whole show, but he even passed his flask on to the other winners.
The "Uptown Funk" singer received the flask from one of his fan clubs and knew that it would come in handy for the show.
He posted on Instagram and Twitter that he was "getting everyone drunk," starting with producer and "Uptown Funk" collaborator Mark Ronson.
Then he moved on to Jeff Bhasker, who won Producer of the Year.
Finally there was Song of the Year recipient Ed Sheeran, who is no stranger to partying.
"Uptown Funk" won Record of the Year and Best Pop Duo/Group Performance.
