At the end of the two-hour finale, Alisan and Adam were the last finalists standing, with Laith placing fourth and Hannah named third runner-up. But it would be a memorable night for Alison, who was crowned The Voice's new champion.
"Oh my god!" Porter, dressed in a sparkling floor-length gown, exclaimed after Carson Daly named her the winner. Aguilera joined her onstage quickly thereafter to celebrate their much-deserved win.
Porter’s victory is a history-maker for The Voice, which, in its previous nine seasons, had never had one of its female coaches come out on top -- a pretty remarkable stat.
The finale also welcomed several of music’s biggest names for a slew of memorable performances: Little Big Town (Pharrell produced their new album), Eagles guitarist Joe Walsh, Sia, Zayn, Alison Krauss, Cee Lo Green, Blake Shelton and an epic duet between Christina Aguilera and Ariana Grande.
Earlier this month, ET broke the news that NBC had planned for Aguilera to perform a duet with a hologram of the late Whitney Houston in the finale, which was later scrapped because it “was not ready to air.”
The Voice returns this fall for season 11 with new coaches Miley Cyrus and Alicia Keys joining Adam Levine and Shelton.
