"The hardest thing to do is transition, keep the train moving. the kid delivered. Huge succesful album, sold-out tour, and won people over...," Braun continued over multiple tweets.

"Congrats to @carlyraejepsen. thought u deserved a best new artist nom, but proud Call Me Maybe got u 2 noms. so proud of u"
