The Celebrity Juice star will record the episode with a live studio audience at The London Studios on July 5, website Applause Store revealed.
Keith Lemon's Bang Tidy Show "promises to be as hilarious and off the wall as Celebrity Juice - the big difference? It's on Saturday night on ITV1," the site claimed.
It continued: "While there's all the usual celebrity guests there's also a talking Orangutan, a door that leads to anywhere, audience games and prizes, a supermarket in the future staffed by old celebrities and you, the audience, can ask Keith anything you want!"
Lemon - created by comedian Leigh Francis - will reportedly finish the show by performing with his celebrity guest.
He most recently co-hosted ITV1's Sing If You Can alongside The X Factor's Stacey Solomon.
