Katie, 31, suffered horrific burns in an acid attack in 2008 and later set up her own charity, the Katie Piper Foundation, to support people just like her.
The mum-of-one's Foundation has now teamed up with the Ideal Home Show to put on a catwalk, called Confidence - The Secret, which will feature a diverse mix of models.
Katie hopes the shows will highlight the journeys the participants have been through, while also giving them the confidence to embrace their individual insecurities.
"I am honoured to launch the UK's first diversity catwalk at the Ideal Home Show and proud to showcase the brave and dedicated models taking part," Katie said today.
"I hope we find some truly inspiring people to join myself and my friends from the Katie Piper Foundation to take part in this every exciting event!"
The catwalk show will be hosted by Katie for three days during its 18-day run and participants will be chosen from the Katie Piper Foundation and Models Of Diversity.
Katie is also offering two people with visible differences the chance to take part too. To be in with a chance, click here!
Last month, Katie walked the runway herself at a special charity show held by Naomi Campbell.
