The model is said to have agreed to appear in the next series of the reality show on Channel 5, along with Blue singer Duncan James, according to The Sun.
The pair will join forces to arrange a couple whom they have never met's wedding day.
A source said: "Katie has plenty of experience with weddings, having organised two herself.
"She and Duncan will put together a no-expense-spared day. It will be outrageous and maybe some of their celebrity pals will turn up for the do."
A friend of Price's added: "A deal isn't signed yet but it looks likely."
Price's first wedding to Peter Andre included a pink horse-drawn carriage, while she also wore a Swarovski crystal-encrusted wedding dress.
The model's 2010 wedding to Alex Reid took place in Las Vegas.
She recently became embroiled in a Twitter row over a repossessed engagement ring with her ex-fiancé Leandro Penna.
