Cameras will follow Lemon around as he films the latest series of hit panel show Celebrity Juice, upcoming movie Keith Lemon: The Film, as well as Jim'll Fix It-style ITV1 vehicle LemonAid.
Lemon said: "Really excited for Lemon La Vida Loca. It's been an incredible ride that I've been riding and now viewers will be able to come along on't ride with me.
"Until the day NASA invents a Keith Lemon simulator then this four-part 45-minute show is the only way people will be able to experience being me, without actually being me. I hope me bird don't mind cameras in't bedroom."
Claire Zolkwer, commissioning editor for comedy and entertainment, joked: "Letting Lemon loose with his own reality show - one thing's for sure, ITV2 is unlikely to ever be the same again!"
Leigh Francis, who portrays the fictional Keith, has been working with ITV since 2008 - before which he shot to fame with surreal Channel 4 sketch show Bo Selecta!.
