No one is more surprised by the results of Tuesday's "The Voice" finale than season five winner, Jamaican powerhouse Tessanne Chin.
The 28-year-old said the news was simply "unbelievable" backstage after the NBC singing competition.
Chin's coach, Maroon 5 frontman Adam Levine, was also thankful to add a second win to his resume while breaking Blake Shelton's three-time winning streak.
Before the winner was announced, Christina Aguilera and Lady Gaga teamed up for Gaga's "Do What U Want" in matching, iridescent outfits.
Aguilera told the crowd that the "Paparazzi' singer was "the most down to earth, real person" she had ever met.
Celine Dion, Ne-Yo, Paramore, OneRepublic and Aloe Blacc also performed during the two-hour season finale.
