The rapper made the confession that - shock - he wasn't born simply Ginuwine.
He told the group how his real name is in fact Elgin Baylor Lumpkin.
Ginuwine told the group: "That's my full name."
Amanda Barrie replied: "That's a wonderful name. I love that name. That sounds like a cartoon character."
"I do animation too!" replied the music star.
Explaining his new name, Ginuwine told the house: "It's just two I am as a person but I couldn't say genuine.
"Then I always envisioned it with a crowd chanting so I wanted a name with three syllables. But I wanted it to represent who I was as a man, as a person."
Amanda quipped: "You'll always be Mr Lumpkin to me."
