Winner Reactions: John Mayer and Jay-Z via Twitter

While the biggest honors from the Recording Academy are handed out live on the Grammy’s telecast, there are seemingly endless others voted on and handed out before one person steps foot on the stage.

Thanks to the power of Twitter, Celebuzz already has reactions from one music heavyweight and news on how a rap king even found out he won.

John Mayer was handed Best Rock Vocal for his track “Gravity,” and immediately blasted out a message to fans and followers.

“Won best rock vocal Grammy for Gravity!” he exclaimed, “Heart is about to explode! That song means the worls to me and to see it get love is a THRILL!”

And while Jay-Z hasn’t always been the biggest fan of the award ceremony, his sister-in-law Solange Knowles was ready with a tweet (aka Twitter message) to let him know he scored a pre-show trophy.

“Told Jay he won in the car via twitter!”

The miracle of technology, as interpreted by celebs.
