'The Masked Singer' Unmasked: Rhino Reveals He Welcomed His Baby Boy Days Before Semifinals (Exclusive)

The Masked Singer kicked off their season 3 semifinals on Wednesday, with the four remaining singers going toe to toe for a chance to move on to the finals and a shot at winning the Golden Mask.

The Night Angel, The Turtle, The Frog and The Rhino hit the stage to try and impress the audience and the panel of celebrity "detectives" -- including Robin Thicke, Jenny McCarthy, Ken Jeong, Nicole Scherzinger and guest panelist Jay Pharoah.

Sadly, after a long, hard-fought season -- and a heartwarming performance of Tim McGraw's "Humble and Kind" -- The Rhino's journey came to an end.

All the panelists made their final guesses as to his identity, and the guesses were all over the board. However, in one of the season's biggest shockers, it was Jeong -- the panel's famously terrible guesser -- who actually nailed it.

After all the predictions were made, The Rhino removed his aviator-inspired mask and revealed himself to be none other than former Major League Baseball pitcher turned country music artist Barry Zito.

Zito spoke with ET on Wednesday, and he opened up about his experience on the wildly weird singing competition and dished on the significance of some of his clues and his elaborate Rhino costume.

One clue with a particularly special meaning was presented during Wednesday's semifinals, when The Rhino showed the judges an adorable baby rhino pin he was wearing on his lapel for the performance.

It turns out, the baby rhino pin represents Zito's newborn baby boy, Rome, whom Zito and his wife, Amber Seyer, welcomed just days before the episode taped.
