Last week's episode unmasked boxing icon Oscar De La Hoya as Fuzzy Peas, setting up the Group A finale as Ant, Coral and Paparazzo.
Paparazzo received the most votes and moved on to The Lucky Six, while Ant and Coral performed in the Battle Royale.
Ant ultimately lost to Coral, who moved on with Paparazzo, with Ant revealed as Aubrey O'Day from the girl group Danity Kane.
After her reveal - which judge Robin Thicke guessed correctly - the 41-year-old singer had a powerful message to her former boss, Diddy, who is now in prison awaiting trial on sex trafficking, racketeering and other charges.

Earlier clue packages from O'Day had hinted that she had gone through quite a lot in her journey through the entertainment industry.
She was part of the girl group dubbed Danity Kane, which was put together by Diddy after he discovered her on Making the Band 3 in 2004.
O'Day was fired from the group in 2008, though she ultimately reunited with the group at the 2013 MTV Video Music Awards.
After her unmasking, the singer admitted, 'It's been a hell of a year,' before delivering a message about her former mentor.
'My ex-boss-- I'ma go there. He calls himself Love. He legally titled himself that. And he uses the love heart to express that everywhere he goes. He's in prison now, and I just want to say to you guys, the love heart is now here,' she said to applause.
Judge Jenny McCarthy-Wahlberg added, 'First of all, I'm so blown away by your voice. I've always known you had a beautiful voice, but you really shined. And I hope you feel the healing at least beginning now, and know that we're being healed by that as well. So I thank you, and I honor you for being here. I honor you for having a voice, and for helping, honestly.'
Robin Thicke added, 'I think also what's great about this-- and you know, since we go way back, and I think what's most important for all of us is that when you have that kind of a talent and that kind of a gift, just keep giving it. And it'll fill your spirit up because you're giving what God gave you, you're giving it back to us. So, thank you. Thank you.'
