LOS ANGELES >> This season’s finale of “The Masked Singer” had a few more surprises than usual.

The Emmy-winning series capped off its 12th season Wednesday night with a festive segment complete with tears, celebrity family cameos and a historic victory that shocked the live crowd and competitors alike. Building up to the big reveal, host Nick Cannon called the finale “probably the most legendary episode ever,” People reported.

The show opened with a number from Season 5 victor Nick Lachey, the former 98 Degrees frontman-turned-reality TV star. Disguised during his season as Piglet, Lachey brought the holiday spirit with a rendition of “It’s the Most Wonderful Time of the Year.”

Next, Season 12 finalists the Buffalos and Wasp delivered two final performances each, after which the audience members cast their votes.

“It was very, very, very close,” said Cannon, sporting a gold sequined Santa hat. In the end, though, the Buffalos came out on top — becoming the first group to take home the show’s Golden Mask trophy.

Upon Cannon’s announcement, one Buffalo dropped to the stage floor and pretended to make snow angels.

The winning trio was later revealed to consist of Boyz II Men members Nathan Morris, Wanyá Morris and Shawn Stockman, who celebrated their victory by performing their 1991 song “Motownphilly.”

The judges unanimously guessed the Buffalos’ identity correctly but were divided about Wasp, who turned out to be Grammy-nominated singer-actor Mario.

Although the Grammy-winning RB group was initially reluctant to join the competition, Stockman told TV Insider they “had such a good time” on the show. Nathan Morris added that the group was especially grateful for their win.

For runner-up Mario, merely “making it to the finale” was enough, he said in his finale voice-over, per Variety.

“This experience has felt like it was made for me. Like I’m finally getting the recognition I’ve been craving,” the “Let Me Love You” singer said. “For a long time in this industry, I felt underrated.”
