The 'My Humps' singer was conducting a telephone interview with KIIS-FM DJ
Ryan Seacrest when he handed her over to his surprise guest - her mom Terri,
who was on the other line.
Terri demanded her daughter tell her if it was true 'Transformers' star Josh
has installed the pole in their bedroom.
Shocked Fergie - who is currently on tour in Europe - stuttered: "Um, I
don't know. I'm going to find out in a few days."
Terri then broke into laughter and joked: "After a year if you're not using
that pole anymore, just turn it horizontal and you can use it as a guard
rail for me."
Josh recently revealed he had installed the pole and that Fergie was taking
dance lessons in preparation for their unusual bedroom fun.
He said: "Fergie is taking lessons, but she won't get on it until she knows
what she's doing, because she doesn't want to look stupid."
