"I know Nick is tired. He's been up all night trying to memorise his kids' names," Jeong told Cannon on the Fox show on Wednesday (16 November), in reference to his 11 children.
That quip opened up the floodgates for others to join in on the roast.
A contestant who went by "Snowstorm" took the stage not too long after and sang Ariana Grande's "Thank U, Next" as a dedication to Nicole Scherzinger, another judge on the show alongside Jeong, Jenny McCarthy and Robin Thicke.
Snowstorm jokingly said: "This song goes out to my favorite fearless lady Nicole, who has had more famous exes than Nick has had baby mamas."
Scherzinger chimed in: Oh, that's a lot of baby mamas."
