'The Masked Singer' Reveals Robo Girl, Beetle Identities and Fans Lose It

Robo Girl and Beetle have been unmasked on The Masked Singer.

The October 26 episode of the Fox singing competition was a Muppets-themed night and featured special guests Kermit and Miss Piggy.

Miss Piggy took on the role of guest panelist alongside regulars Robin Thicke, Ken Jeong, Jenny McCarthy Wahlberg and Nicole Scherzinger for the evening.

On the episode, hosted by Nick Cannon, new contestant Beetle competed against the trio of the Lambs and the Queen of last week's "Andrew Lloyd Webber Night," Robo Girl.

Robo Girl returned to The Masked Singer to perform for the second week in a row thanks to the new format that only allows one contestant to go through to the next round each week.

In the first round of votes, Beetle received the fewest, meaning they were unmasked first. Robo Girl and the Lambs then performed again in a "Battle Royale" which the Lambs won, meaning they advance to next week with their identity still a secret and Robo Girl was unmasked.

Newsweek has everything you need to know about which celebrities have been revealed on The Masked Singer.

Who Is Beetle on The Masked Singer?

Beetle impressed the judges with their performance of the Frank Sinatra song "The Way You Look Tonight," after which the panel guessed they could be Mike Myers, Jerry Springer, Rowan Atkinson or John Larroquette.

After their first performance, Beetle, who fans had previously thought could be Ringo Starr, Paul McCartney or Leif Garrett, was unmasked due to receiving the fewest votes from the audience.

Former talk show host Jerry Springer was revealed as the celebrity behind the Beetle costume.

Who Is Robo Girl on The Masked Singer?

Robo Girl took on the Lambs in the "Battle Royale" but lost out when the judges cast their votes, meaning they were unmasked.

After singing "Call Me" by Blondie, Robo Girl was unmasked to reveal actress Kat Graham.

Fans had previously guessed that Graham was Robo Girl after her clues pointed to her role as Bonnie Bennett in CW drama The Vampire Diaries.

Scherzinger, who is friends with Graham, was especially shocked by the reveal and said: "When you know the person, when they're your friend and they unmask, you're like, 'Oh dang! I can't believe I didn't get it!'"

Having had their predictions confirmed for Robo Girl and their guesses blown out the water with Beetle, fans had huge reactions to both the reveals.

Taking to Twitter after the episode aired, one viewer wrote: "#TheMaskedSinger omg [The Beetle] is Jerry Springer @jerryspringer you did wonderful job sorry u had to go."

While another simply posted: "JERRY SPRINGER?" alongside a series of shocked emojis.

"It is Kat Graham! Knew it! #MuppetsNight #TheMaskedSinger," wrote another viewer.

As another celebrated: "YAS I WAS RIGHT IT WAS KAT GRAHAM!!!!! #TheMaskedSinger."
