Who Are the Walrus and Milkshake? 'The Masked Singer' Identities Revealed

Walrus and Milkshake were the two costumes to be unmasked on the latest episode of The Masked Singer, which was also the Fox show's 100th episode.

The special milestone episode had been pushed back from its usual Wednesday slot to Sunday evening to accommodate the World Series baseball tournament, so fans were even more excited than usual to for the show to hit their screens.

To celebrate the 100th episode, The Masked Singer aired a '90s-themed special, featuring special guests and panelists Robin Thicke, Ken Jeong, Jenny McCarthy Wahlberg and Nicole Scherzinger dressed up in that decade's styles.

The show opened with DC Glenn and Steve Rolln from Tag Team performing their 1993 classic "Whoomp! (There It Is)," before it was time for Walrus, Milkshake and reigning Queens the Lambs to take to the stage.

Newsweek has everything you need to know about The Masked Singer's 100th episode, including which celebrities were unmasked and what they performed.

Who Is Walrus on The Masked Singer?

Fans initially believed Walrus could be NSYNC star Lance Bass due to his clue being a fish, but several more hints were dropped during the episode that steered viewers away from this prediction.

Bass also made a surprise cameo on stage after Walrus' performance as part of the '90s theme, ruling himself out of the running.

Walrus' clues included the phrase "full house" and that he once tap-danced for a '90s talk show legend.

After his performance of "Two Princes" by Spin Doctors the panel guessed the Walrus was perhaps John Stamos, Joey Lawrence or Mario Lopez.

Ultimately judge Robin Thicke was proved correct with his guess of Joey Lawrence, after the Melissa and Joey star was knocked out during the first round.

Who Is Milkshake on The Masked Singer?

Ahead of his performance, Milkshake revealed some clues for his identity, which included the fact that he has been "making hits since he was young" and can "throw a knockout punch."

Milkshake then performed "Jump On It" by Sir Mix-a-Lot and the panel guessed it could be LL Cool J, DJ Jazzy Jeff, or T.I. behind the mask.

The Lambs then returned to the stage to sing "Ironic" by Alanis Morissette, leading the judges to question if the trio could be The Corrs, SWV or The Chicks.

Walrus was unmasked so the Lambs and Milkshake then went head to head, each singing their own rendition of "What is Love" by Haddaway.

Milkshake was eliminated and his identity was revealed as American football running back Le'Veon Bell.

So far on The Masked Singer Season 8, William Shatner, Montell Jordan, Chris Kirkpatrick, Eric Idle, Jeff Dunham, Daymond John and The Brady Bunch stars Mike Lookinland, Christopher Knight and Barry Williams have been unmasked.

Mario Cantone and Gloria Gaynor, Jerry Springer and Kat Graham, and now Lawrence and Bell have also been revealed as contestants.

Meanwhile, the only characters to remain unmasked so far are Harp, who fans think is Glee actress Amber Riley, and the Lambs, who viewers believe are Wilson Phillips.

The Masked Singer has a new format this season which sees only one costume move on to compete the following week.

So far there has been two, three-week long, rounds, with Harp and the Lambs winning their respective rounds and securing their spot in the semi-finals.

The third and final three-week round kicks off on Wednesday and the winner of that round will join Harp and the Lambs in the semis.

The Masked Singer airs Wednesday nights at 8 p.m. ET on Fox.
