Huge night for Bruno Mars and Anderson .Paak as Silk Sonic, winning all 4 awards they were nominated for at the Grammys.

They took home trophies for Record of the Year and Song of the Year for “Leave The Door Open,” which also won Best R&B Performance (a tie with Jazmine Sullivan’s “Pick Up Your Feelings”) and Best R&B song.

Ah, but the way they reacted to that last win... it's going down as a classic!
