Peacock is Donny Osmond covered in feathers 

My guess for who the Peacock is the one and only Donny Osmond. He started his career out young and hasn't stopped yet since. After hearing the peacock sing for the first time, I recognized the voice from the countless memories of watching Joseph and the Amazing Technicolor Dreamcoat and of course the one song so many of us know Be a Man. If you want to hear the peacock's performance here is The Masked Singer.

You can find Monster in a gray Cadillac because he's T-Pain 

The Monster has been prejudged and outcasted, and after hearing his voice I believe that this secret singer is T-Pain. You might think, what? T-Pain? He uses autotune and is a rapper, he can't sing. Well my friends, gather close and click this link to listen to a mashup of T-Pain classics but with him just singing without autotune. Here is the Monster's performance of Don't Stop Me Now, and now sit and wonder who is behind this fuzzy costume.

The mysterious spell has lifted because Unicorn is Tori Spelling 

The Unicorn talks about how she is called "Bird," and Tori is known for her nickname "Bird." Add in the fact of the other clues like she has grown up with a magical in Hollywood with famous family. Unicorn also held five little baby unicorns, and Tori has 5 kids. Coincidence, I think not people!!! She talked about how she used to the runway; maybe she was talking about an airport runway.

Rumor has it that Lion is Rumer Willis 

In her second appearance, there is the video of her reading a newspaper with the headline, "Gold Found in Hailey." Rumer lives in Hailey, Utah right now. The Lion also has promoted her using her voice not just for singing but for sharing what she believes in and pushes her lion pride to also stand up for what they believe in. Rumer is a huge activist for women's rights. No matter who is underneath the mask, I am part of Lion's pride.

Hop on the Joey Fatone is the Rabbit bandwagon 

The Rabbit has a comedic persona even though he is kind of a creepy, twitchy Trix rabbit gone bad. The Rabbit's singing seems to fit his Joeys tone and voice. Some people are saying that Joey isn't the Rabbit because he did an interview and denied it but think about it. Why would he say he was the rabbit when the entire show is about anonymous till either you lose or win. I know people are saying are saying JC Chasez is actually the Rabbit, but listen to his voice, and they are different. If you don't believe me, then bye bye bye...

Alien's out of this world performances point towards La Toya Jackson 

Alien expressed being only a young girl before her family came into fame, and the Jackson 5 stared the young Jackson family. Also, another clue that points to Jackson is in the second episode it shows five aliens in a row after mentioning that anonymity is an "alien" concept. Another clue is the snake toy in the fourth episode; La Toya is famous for posing in a magazine picture with a snake.

Ricki Lake and Raven both start with R because they're the same person 

Raven is treating this show as a therapeutic approach to heal from some painful situations that have happened to her in the past few years. Ricki Lake lost her ex-husband recently. The Raven expressed how she has listened to people, but also talks a lot. Ricki Lake had her own talk-show for a long time, and with that career, you do a lot of listening and talking with the guests and audience. Another major clue that makes me think it is Ricki is that the Raven says it is from Hudson and the number 1968 appeared on the screen. Ricki is from Hudson and was born in 1968.

The Empress Bee is Gladys Knight 

From the first episode featuring this masked celebrity, she used the clue of being an empress, and that specific word has stood out to me ever since. Gladys Knight is known as the "Empress of Soul," and with Bee's beautiful singing voice is very similar to Gladys Knight. The Bee has expressed how she wants to stay with the times and sing current songs, giving a hint to her older age.
