The Celebrity Big Brother winner and X Factor star announced on Twitter that he will appear on every edition of the Keith Lemon panel show, which returns to ITV2 tonight (February 28).
"Now I can say!! Catch me on the new series of @celebjuice every Thursday at 10pm on @itv2 with @lemontwittor xxxx," he wrote.
Clark also posted a behind-the-scenes photo of himself and Lemon dressed up in his outlandish Judges' Houses outfit and sat next to a dummy that appears to be of his mentor Nicole Scherzinger.
Is it not yet known whether Clark will replace Rufus Hound as a recurring Celebrity Juice panelist, or simply take part in weekly challenges, as Jedward and the cast of Coronation Street have done in the past.
Kelly Brook will be filling in for new mother Fearne Cotton as Holly Willoughby's rival team captain in the upcoming series.
Celebrity Juice airs on ITV2 at 10pm.
