Celebrity chef Gino will replace Holly as team captain, so he will compete against rival captain Fearne Cotton in the comedy panel show hosted by Keith Lemon.
This Morning presenter Holly, who is expecting her third child with husband Dan Baldwin, kicked off the show's 12th series last Thursday, but Gino will take over from this week onwards.
The news was announced last night (15 September) and I'm a Celebrity...Get Me Out of Here! star Gino said: "I actually can't believe it's true… it's going to be the gig of my year!"
Keith - real name Leigh Francis - added: "Looking forward to having me old pal from Sheffield cover for Holly whilst she's sprouting.
"I don't know how he's going to keep up that fake Italian accent for a whole series but it's going to be 'fantastico' as Gino says, or when he's out of character, 'reet good'!"
Elsewhere, Britain's Got Talent judge Amanda Holden has been confirmed to take over from Holly on This Morning.
Celebrity Juice continues Thursday 18 September at 10pm on ITV2.
