'The Masked Singer': The Tree Gets Cut Following Emotional, Powerful Quarterfinals Round

After a night of truly stunning performances, the judges and audience are tasked with choosing who would be going home, and which singers would move to the semi-finals.

Despite slaying her Lady Gaga number, The Tree ends up on the chopping block.

Panelists' Final Guesses:

Robin says Amy Sedaris

Nicole says Amy Sedaris

Jenny says Ana Gasteyer

Ken says Bebe Neuwirth

T-Pain says Mariah Carey, "Because I wanna see Nick panic."

After the traditional stuggle-with-the-mask, The Tree reveals herself to be Saturday Night Live star Ana Gasteyer!

Jenny is overwhelmed with excitement over being right, and Ken once again is embarrassed, because he's acted with her before!

To close out the show, Ana sings an unmasked version of "The Edge of Glory," and we all get to laugh at how incredibly forgetful Ken is week after week.

The Rottweiler comes out and brings the entire theater to tears with an amazing performance of "Someone You Loved" by Lewis Capaldi that earns him a standing ovation from the panel and a whole lot of misty eyes from the audience.

Nicole says, "I think it's the most vulnerable and honest performances we've ever seen on that stage."

As a clue, The Rottweiler tells the panel, "I have been on the same list, and it was not People's Sexiest Man Alive."

Panelists' Guesses:

Robin thinks it could be Glee star Darren Criss.

Nicole thinks it could be Jared Leto, which Jenny agrees with.

Ken thinks it's Bow Wow, because the costume is a dog.

T-Pain says, "Whoever it is, it's a really damn good singer."

The Rottweiler:

- Says he's trying to be "Zen."

- We see meditation mats.

- He says, "I like to imagine myself in a tranquil pool, swimming from the deep end to the shallow."

- He says, "Tonight, I am an open book."

The Tree is certainly upping her festiveness this week, with a powerful, fun and wild performance of Lady Gaga's "The Edge of Glory" that involves quite a few high notes and a whole lot on confetti and lasers.

"That was really good!" T-Pain said. "I loved the pageantry of the whole thing."

As a clue, The Tree tells the panel that she's "shared the stage and a standing O with one of you."

Panelists' Guesses:

Ken thinks the Broadway and sitcom clues imply The Tree is Frasier star Bebe Neuwirth.

Robin thinks it's Rachel Ray.

T-Pain says the Christmas references mean it's Mariah Carey.

The Tree:

- Says, "If I'm being honest, it can get lonely under this mask. I miss the collaboration. I miss my friends."

- We see blue poms poms, and says she needs people's "cheers more than ever."

The Flamingo is in this to win this, and she truly showed it with an incredible performance of Fleetwood Mac's "Go Your Own Way."

"It was sexy, it was sassy, it was seamless, it was super," Ken marvels.

As a clue, The Flamingo says, "I shared some couch time with one of you in 2013."

Panelists' Guesses:

Ken says it's "someone I know very well" and guesses Hilary Duff.

Jenny says it's Adrienne Bailon (which we agree with).

Robin is sticking with his Fantasia bet.

The Flamingo

- Says she used to be "clueless."

- She references old TV shows including Sister Sister.

- Says, "I've got to step up."

After a somewhat lackluster Week 8, Thingamajig returns this week with a stunning performance of "Ordinary People" by John Legend that truly shows off his vocal range.

"That was amazing," T-Pain says. "That was indistinguishable from John Legend. It must be John Legend in that costume, on stilts."

As a clue, Thingamajig tells the panel, "I've collaborated with the same artist as one of you."

Panelists' Guesses:

Nicole says that it could be NBA star Markelle Fultz.

Robin still thinks it's Montell Jordan.

Jenny doesn't really known who it could be, but she's sure Thingamajig is Nicole's future fiance.

Thingamajig:

- He holds a guitar.

- He hands out postcards with 'MVP' on them.

- Says he doesn't have time to get "crabby."

The Leopard once again delivered a regal performance, belting out an emotional, heartfelt rendition of "We Are Young" by Fun.

While The Leopard doesn't bust out any Fox-like dance moves, he knows how to own the stage simply with his voice.

When asked what The Leopard has in common with one of the panelists, he hints, "I was presenting an award on an awards show that included one of you, and I was wearing a custom leather outfit."

Panelists' Guesses:

Jenny suggests it could be Eric Benet.

Robin says it's hard for him to hear anyone else but Seal, and Robin agrees.

Ken randomly guesses it's Enrique Iglesias, for no real clear reason.

The Leopard:

- We see him playing tennis.

- There's a reference to tofu.

- We see a knocked-over motorcycle toy, implying a crash at some point.

- We see a check for $20 million.

The Fox decides to show off another side of his vocal talent with an incredible performance of "Blame It" by Jamie Foxx, featuring T-Pain.

The song choice -- which might be an effort to appeal to tonight's guest star, or to convince the panelists he might actually be Jamie Foxx -- was a great selection for his voice.

As an extra clue, The Fox tells the panel, "I have spent one of the best weekends of my life with one of you."

Panelists' Guesses:

Nicole and Jenny think it could be Jamie, and Ken loudly agrees.

Robin says he thinks it might be Wayne Brady, but admits he doesn't get the superhero references.

T-Pain thinks it might be Lenny Kravitz. (Which is a solid guess, but it's Wayne Brady, I believe it in my heart!)

The Fox:

- We see a book on how to break up with someone.

- Says, "I wanna fly away."

- Says, "I've learned I don't need to hide behind my superhero costume anymore."

- Says he feels "unchained."

The Masked Singer on a Tuesday?! Well, here we are, kicking off the season 2 quarterfinals with all six singers hitting the stage to duke it out to secure their place in tomorrow's semi-finals.

It's going to be an exciting night! Everyone who is still in the competition has a killer voice and know how to own the stage!

Plus, T-Pain is the guest panelist, so that's gonna be a lot of fun. Let's do this thing!
