Season 10 of NBC's hit reality singing competition, The Voice, came to an end Tuesday night, but not before a new winner was crowned. At the end of the two-hour finale—which included performances from chart-toppers like Zayn Malik, Ariana Grande, and Sia—it was Christina Aguilera's mentee, Alisan Porter, who came out the victor. Porter made history for Aguilera as well, who became the show's first female coach to have a winner. "Tonight is a true victory for women" Aguilera later said backstage.
Aguilera provided another highlight when she left her red chair for a surprise duet with Grande. Halfway through Grande's performance of her hit track "Dangerous Woman," Aguilera joined her fellow pint-size pop star for the second half of the song, lending her incomparable pipes to her sultry single.
Congrats to Team Christina—winners all around!
