It will be the curvy model’s first major TV gig since fronting the Big Breakfast for five months in 1999 and reality show Celebrity Love Island in 2005.
She is standing in for Radio 1 DJ Fearne Cotton, who is taking time out from the ITV2 panel game to have a baby.
Keith – real name Leigh Francis – said at this week’s National Television Awards: “Doing Celebrity Juice is exciting – especially when you have a new captain who has bigger bangers than Fearne Cotton.
The comic quipped: “I didn’t think we could replace Fearne but now we’ve got Kelly I hope Fearne don’t come back.
Only joking – hope you have a smooth delivery Fearne. Miss you. Just hope Holly don’t get jealous.”
Kelly said: “I will have a lot of fun keeping Fearne’s seat warm until she returns.”
