  • Who is Grandpa Monster on The Masked Singer season 5? Below, we reveal what the internet is guessing at the moment.

  • Based on what we know so far, we'd say Grandpa Monster is Mario Lopez.


Here to prove age is just a number is Grandpa Monster, The Masked Singer's newest celebrity to don a version of the beloved monster mask from past seasons. This old-timer might use a walker to get around, but he has more than enough talent to tackle the competition. Plus, how can anyone resist that big toothy grin? We can't wait to see what lessons this living legend has to impart on his younger cohort.

So far, we don't know much about this colorful creature, but here are the clues we have to go on.

Who is Grandpa Monster on The Masked Singer?

First, let's look at the clues:

  • Grandpa Monster has one huge green eye and uses a walker with tennis balls on the feet.

  • He tells us he's "never too old to slay."

  • In his clue package, we see Grandpa Monster in a classroom with a number 6 etched on the chalkboard behind him.

  • He mentions how he was "always acting out" as a youngster, but a teacher convinced him he was "smarter than the character I was playing." Could that mean he's an actor?

  • He says he's still working to shake his "bad reputation" and we see a kettlebell that's 6.2 tons on the beach.

  • We also see Grandpa Monster on a beach surrounded by palm trees. It looks a lot like a retirement community!

Despite Grandpa Monster's apparent age, many fans seem to think his costume is just a facade, and it's really a younger celebrity behind the mask. "How much do you want to bet that this is someone young," one fan wrote on Instagram. If that's the case, then Mario Lopez seems to be a popular option.

Still, others think Grandpa Monster must be an NFL player. The Masked Singer revealed this season's contestants will include three athletes who've appeared in a Super Bowl, and Grandpa Monster could be one of them due to the Xs and Os making up the "6" on the chalkboard in his clue package. "The components making up the 6 look like the components that make up an NFL play diagram," one fan on Reddit theorized.

We'll have to wait and see when this energetic elder takes the stage next.
