The Celebrity Big Brother winner will discuss his failed relationships with Katie Price and Chantelle Houghton in the tell-all book.
"He had already started jotting down notes on Jordan and the Chantelle stuff is just as juicy," a friend told the Daily Star.
Houghton confirmed earlier this month that she had split from Reid, explaining that she had "no option" but to end the relationship. The pair have a daughter together named Dolly.
He split from Price back in January 2011, but the former glamour model recently revealed that they still aren't fully divorced.
Reid had been attempting to win Houghton back, recording a video message via Now magazine in which he declared his love for her.
"You can't keep venting your anger on me in your column. I'm trying to work things out... every couple argues. I know you love me. I hope you love me. Let's sort this out," he said.
