Alison revealed this new during an interview on Tuesday's This Morning.
She was on there to promote her new documentary, Back To School, which airs on Tuesday 6th October at 9pm on ITV - more information on the documentary can be found here.
Speaking to Alison on Tuesday's This Morning, Phillip Schofield said to Alison: "You're also going to be guest editor on This Morning!"
Alison replied: "I am - I'm going to whip you in to shape!"
Holly Willoughby added: "So, being editor on this is where all the decisions are made, you shape the show, so what is your show going to look like?"
Alison continued: "I'm not gonna be scary. It's just going to be a fun packed show, with a little bit of depth, because I have got a little bit of depth. I might change it up a bit here, I don't know, I might... It's gonna be great."
UPDATED: Alison will guest edit the show on Friday 23rd October, and present the show with Dermot O'Leary.
Alison said: “It will just be a joy! There will be nothing about lockdown or coronavirus. There’ll be a lot of recipes and food… and maybe a little bit of fashion and fun. It’s going to be great and I’m excited to be the boss!”
Martin Frizell, editor of This Morning, said: “I still can’t quite believe I’ve agreed to this... But yes, on Friday our Alison Hammond will be stepping into my shoes and taking charge of This Morning. She will brief Dermot, decide on the topics and items of the day, and be in the gallery calling the shots and giving her unique style of guidance to the team. But you know what, I think she’ll be great – she knows the show inside out and I think viewers will be in for a real treat.”
This Morning continues weekdays at 10am on ITV.
