Comedian Jack Whitehall has been dabbling in hosting over the last few years, and he’s continuing that on Fox’s new game show Nation’s Dumbest. The series features Whitehall putting celebrity contestants through elementary-level quizzes and challenges, with the cast hoping to be eliminated before they’re declared the “nation’s dumbest.”

The role allows Whitehall to show off his comedic timing by mocking the celebrity contenders, while introducing him to a brand-new audience of viewers who may want to know more about his life off-camera. That includes his romantic history and relationship with wife Roxy Horner. Scroll down below to learn more about Jack Whitehall’s relationship with Roxy Horner, their past romances, and more.
