T-Pain was crowned the winner of Fox's "The Masked Singer" costumed singing competition on Wednesday night.

The rapper wore a monster costume and was known only as Monster throughout the 10-episode season of the show, which Nick Cannon hosted.

His identity was only revealed after his victory was announced.

The judges were Robin Thicke, Jenny McCarthy, Ken Jeong and Nicole Scherzinger.

"That was the most humbling thing I've ever been through," T-Pain said as he held his trophy during Wednesday's finale.

"I chose the monster costume myself. It just spoke to me. It said, 'That's you in one-eye form.' I really thought I was going to be out in the first episode because everyone tells me I have such a recognizable voice. I was definitely wrong about that."

T-Pain beat out his fellow disguised finalists Donny Osmond -- dressed head to toe as a peacock -- and Gladys Knight -- concealed in bee regalia -- for the honor.

Previously eliminated, costumed contestants included Joey Fatone, Rumer Willis, La Toya Jackson, Ricki Lake, Tori Spelling, Margaret Cho, Terry Bradshaw, Tommy Chong and Antonio Brown.
