Boy George and 'American Ninja Warrior' host Matt Iseman squared off in the finale.

Boy George pulled out all the stops in the final challenge of The New Celebrity Apprentice, but his bid fell short as American Ninja Warrior host Matt Iseman was crowned winner Monday during the NBC show's 2017 season finale.

For the final task Boy George brought out the star power of Caitlyn Jenner, Mel. B., and "cruise director" Carson Kressley before capping it off with a performance by Natasha Bedingfield, who sang "Pocketful of Sunshine" before joining the Boy for a duet of the hit "Karma Chameleon" in a final bid seeking to gain favor with Carnival Cruise Lines.

Iseman, however, scored major points with the appearance of Carnie Wilson, who appeared with her group Wilson Phillips for a performance of Billboard Hot 100 topper “Hold On.”

Team Boy George raised $445,925 for his charity, Safe Kids Worldwide, but Team Matt crushed it with $573,329 for The Arthritis Foundation, which cemented host Arnold Schwarzenegger's decision to select Iseman as the winner.

"You kicked some serious butt, task after task," he said.
