‘The Masked Singer’ spoiler: The Flamingo is …

Six celebrities take to the stage in the fourth episode of season 2 of “The Masked Singer” on Wednesday (October 16). Each of them is completely clad in an costume with their face obscured behind an elaborate mask. After each pair of contestants sings, one moves on and the other returns for a sing-off. At the end of the show, the four judges — Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke  — give the boot to one of these half dozen stars hoping to win season two of “The Masked Singer.”

It is only at this point that host Nick Cannon will have the contestant take off their mask. If you can’t wait till the big reveal, keep reading as we’ve got “The Masked Singer” spoilers, including the name of the Flamingo, one of the six contestants on episode 4. (Be sure to check out our best guesses for the other five celebrities: the Black Widow, Butterfly, Leopard, Skeleton and Thingamajig.)

We think that the Flamingo is Adrienne Bailon Houghton, the one-time singer in  The Cheetah Girls who is one of the co-hosts on the talk show “The Real.” In her first appearance, the Flamingo covered the hit “Sucker” by the Jonas Brothers. Her vocals were good enough but it was her dance moves that really impressed the judges.

The clues package for the Flamingo is full of the color pink and references to “Zootube.” Houghton doles out advice on her YouTube series “All Things Adrienne” and is obsessed with the color pink.

What do you think of our guess? Who do you think is hiding inside the Flamingo costume? Sound off in the comments section below.
