In this exclusive sneak peek at Wednesday's new episode, Nicole is passionate about her guess, following a performance and some clues about Baby Mammoth.
"I'm getting Melissa McCarthy vibes? Your cousin?" Nicole says, as Jenny nods and smiles.
"Missy, are you in there?" Jenny jokingly calls out to Baby Mammoth, who stands quietly on stage next to host Nick Cannon.
"Last week, in the clues, it said 'Cheer.' Little known fact, Melissa McCarthy was a cheerleader in high school," Nicole continues. "Also, there was a match, and Melissa McCarthy was in The Heat with Sandra Bullock."
"It could be her," Jenny says. "I could totally see her doing it, and her kids love the show."
"That's a good guess!" Robin Thicke adds with a smile.
Either way, fans will be able to see Baby Mammoth face off against the Frog Prince, Space Bunny and Queen Cobra as The Masked Singer's season 7 competition continues to heat up on Wednesday at 8 p.m. ET/PT on Fox.
