Every season on "The Voice," the four celebrity coaches are joined by artists and friends who act as advisors for their contestants during the show's Battle Rounds.
The advisor working with Christina Aguilera's team will be Grammy-nominated singer-songwriter Ed Sheeran, who co-wrote Taylor Swift's "Everything Has Changed."
He also duetted with Elton John and has written tracks for One Direction. His debut album "+" has been certified quintuple platinum in the UK and gold in the US.
Sheeran will appear during the Battle Rounds for "The Voice" Season 5, which will air October 14th and 15th on NBC.
