A newly published memoir claiming to be written by Sean “Diddy” Combs‘ late ex-girlfriend Kim Porter is being called out as “fake” by Combs’ attorney. Porter’s family is also “exploring” legal action, a source close to the family tells PEOPLE.

KIM’S LOST WORDS: A journey for justice, from the other side… was recently published on Amazon on Sept. 6. After Combs, 54, was indicted on sex trafficking, racketeering and prostitution-related charges on Sept. 17, the book rose to the No. 1 spot on the platform’s Literature & Fiction list.

A brief sample of the 58-page piece, noticeably filled with typos and inaccuracies, details alleged disturbing and graphic sexual encounters with Combs and other well-known celebrities, as well as alleged physical abuse from the music mogul against Porter.

Combs’ attorney Erica Wolf says in a statement to PEOPLE that the memoir is “fake,” “offensive” and “a shameless attempt to profit from tragedy.”

The cover features a photo of the model, who died at 47 of lobar pneumonia in 2018, and says it is written by “Jamal T. Millwood” for “Kimberly A. Porter.” Chris Todd (real name Todd Guzze) self-published the book under the Millwood pseudonym.

“Chris Todd has no respect for Ms. Porter or her family, who deserve better,” Wolf tells PEOPLE. “Unlike the fabrications in his sickening ‘memoir,’ it is an established fact that Ms. Porter died of natural causes. May she rest in peace.”

“Kim Porter’s family is exploring all their options” according to a source close to the family, specifically regarding legal action against the publisher and those involved.

“Kim Porter never authored a manuscript, and any claims suggesting otherwise are entirely false and fabricated,” another sources close to the family adds. “The baseless pages in the book not only misrepresent Ms. Porter’s lived experience and legacy, but also continue to cause unnecessary distress to her loved ones. Kim Porter has four children, two of whom are still minors, and all of whom no longer have access to their father while he is detained awaiting trial. Chris Todd, who is credited as the publisher, has no connection to Kim Porter or her family.”

PEOPLE spoke with Todd about the veracity of his book’s contents on Tuesday, Sept. 24.

“Do you think Chris Todd would risk his ass and rep on something that was fake??” Todd replied, addressing himself in third person. “Number one on Amazon.”

“If somebody put my feet to the fire and they said, ‘Life or death, is that book real?’ I have to say I don’t know. But it’s real enough to me,” Todd said in a separate interview with Rolling Stone. “Sometimes you have to just put it out there. Maybe not 100% of the book is true, but maybe 80% is. That is to get those people to come forward and either corroborate or deny [the claims], and that helps me as an investigator to know the truth.”

Porter and Combs’ off-and-on romance began in the 1990s. They welcomed son Christian in 1998 and twin daughters, D’Lila Star and Jessie James in 2006 before calling it quits in 2007. Combs also helped raise Porter’s son, Quincy Brown, whom she welcomed with R&B singer Al B. Sure in 1991.

Sure, 56, also slammed the memoir as fake and “unauthorized” in an Instagram post on Monday, Sept 23.

He shared snippets of the book as well as photos of him and Porter and wrote in part in the caption: “Unfortunately, Kimberlina was taken from us way to soon and before she could complete her true thoughts before this FAKE Unauthorized EDIT released on AMAZON which the disappearance of her computer and vital evidence raises significantly more questions.”

He also warned of a “significant suit headed right for the heads of the responsible parties.”

Ahead of the book’s release, Porter’s close friend Eboni Elektra also shared via Instagram that Porter did not write a secret book and “would never do a such a thing.”

Meanwhile, Combs is being held at Brooklyn’s Metropolitan Detention Center after being denied bail twice while he awaits trial. He is due back in court in early October.
