Fox orders 13 'Moment of Truth' episodes
The show, which airs before American Idol, has contestants battle it out for cash prizes by answering embarrassing questions about their lives.
Its ratings have pleased the network, although Fox also confirmed there will be slight alterations to the format due to viewer complaints about the question response times from contestants.
Talking about the show's successful ratings, Fox boss Mike Darnell said: "That means that the people who came to see it liked it. I feel thrilled and confident."
