Billie Eilish preformed "Happier Than Ever" at the GRAMMYs last night and it's caused quite the stir.
She absolutely killed her performance, as she typically does, but the way the stage was set has fan speculating a collab... with Harry Styles.
Harry recently announced his new album "Harry's House" with a picture of him inside an upside down living room.
And during Billie's performance last night, the stage was set with her in an upside down living room with a couch above her.
Now fans are wondering if this was a little Easter egg and is teasing a collab between the two. Seems more like wishful thinking, but could you imagine a better duo?!
