The glamour model was signing copies of her latest book at the Bluewater shopping centre in Kent and invited The Only Way Is Essex star Childs to meet her in person.
A spokesperson for Price told the Daily Mail: "Katie Price did not see Amy Childs today. Amy sent Katie a text asking if she could jump the large queue and get a signed copy of her book at her Bluewater signing.
"Katie was more than happy to help out Amy and responded saying she was sat in the manager's office having lunch and invited Amy to join her and pick up a copy of the book. She was looking forward to seeing Amy but got no reply."
Price has been accused of being "fixated" by Childs, who admitted to being close to tears on meeting her ex-husband Peter Andre.
