Kardashian book author Ian Halperin is hinting that Caitlyn Jenner may soon become a man again as the former Olympian supposedly regrets going through the sex change.

The author, who wrote “Kardashian Dynasty: The Controversial Rise of America’s Royal Family,” revealed to The Wrap that he found out about the information as he was researching for his book.

He said one of his sources shared that things have not been easy for Caitlyn Jenner. In fact, “it’s been very hard.” Several sources also told him that the reality star has been miserable for months. “One source confirmed to me Caitlyn has made whispers of ‘sex change regret,’ hinting she might go back to being Bruce Jenner,” said the author.

However, amid the alleged regret, Kris Jenner’s ex-husband is thrilled to champion transgender people.

“She’s thrilled she has raised awareness about how transgender people have long been discriminated against but I think there’s a chance she’ll de-transition in the next couple years,” a friend of Caitlyn Jenner supposedly told Halperin. The said source added that the whole thing has been more difficult than Caitlyn Jenner had anticipated and that going back to being a man would not “surprise anybody in her inner circle.”

Another reason she might “de-transition” is because she reportedly still likes women and “wants to meet the right one.”

Caitlyn Jenner’s representative, however, slammed the claims, branding it as an “idiotic report.” “Not worth commenting on such an idiotic report,” shared the representative to Daily News. “Of course it’s not true.”

Her transition has been a subject of the recent episode of Keeping Up With the Kardashians shown on May 8.

Caitlyn Jenner got upset when Khloe Kardashian revealed in a Howard Stern interview that the former Olympian was not completely honest about going through the transition. After the interview, the reality stars have not spoken to each other until they met at Kanye West’s fashion show.
