She's invited Derek to be her flatmate when he comes to Britain to appear in the new series of Strictly Come Dancing.
The X Factor judge, 26, is expected to sell the home she owns with Ashley Cole in Godalming, Surrey, and has been viewing a luxury apartment in London.
'Derek has been there for Cheryl through some tough times. Now she wants to bring him into her life even more,' an insider tells the Sunday People.
Cheryl was introduced to Derek, 25, last year by Strictly Come Dancing judge Bruno Tonioli.
She has never talked about the depth of their friendship.
