The presenters made their top three placings predictions for Hamilton, Sam Attwater and Chloe Madeley on This Morning last week.
Revealing the way they thought the results would go, Willoughby showed that she had expected the children's TV presenter to come first, with Attwater and Madeley in second and third position respectively.
Her co-host also failed to correctly predict the finishing order, expecting the ex-EastEnders star to lose out to Hamilton.
Last night's final saw Madeley finish third, while Attwater was crowned winner with 63 per cent of the public vote following his performance of the bolero.
The actor has admitted that he is "overwhelmed" to have received enough support to win the skating competition.
