The host of the ITV1 celebrity gameshow will be joined by his wife Stephanie during the upcoming fourth series, reports The Sun.
The tables will be turned on the This Morning presenter, as the couple will be quizzed on each other's habits and personality traits.
A source said: "Phillip has been making husbands and wives grill each other for years so it's only right that he endures it himself.
"He's been with Stephanie since 1993 so the researchers have plenty to work with."
Schofield will present the upcoming series on his own after Fern Britton left after series three.
Ten episode will be aired on ITV1 this summer, with other celebrities including John Prescott, Stacey Solomon, Antony Cotton, Michael Owen, Paddy McGuinness and Warwick Davis.
