Speculation is mounting that Meghan Markle could be on the cusp of releasing her own memoir, as she and Prince Harry continue to seek new avenues for income following their severed deal with Spotify and discontinuation of Markle's "Archetypes" podcast.

Louise Roberts, a columnist for News Corp, and Bronte Coy, an entertainment reporter at News.com.au, made these conjectures during their recent guest appearance on Sky News Australia's "The Royal Report."

Roberts suggested that in the wake of their cancelled Spotify agreement, which was reportedly worth $20 million, it is possible that not only could Prince Harry pen a second memoir to follow his book "Spare," but his wife, the former "Suits" actress, might also have a tell-all publication in the pipeline.

"I think Meghan is a dark horse here," Roberts stated. "I think it's time for her to unleash her tell-all memoir because of the whole Oprah [Winfrey] thing. Although the royals can't really control Harry, they certainly cannot control Meghan. And she would talk and talk and talk, so there's no way of nipping that in the bud at all."

In their 2021 sit-down interview with Oprah Winfrey, the Sussexes candidly discussed their decision to relinquish their royal responsibilities and levelled several allegations against the monarchy. They delved further into their love journey and departure from royal duties in their 2022 Netflix documentary "Harry & Meghan." Prince Harry, meanwhile, made several accusations against his elder brother, Prince William, and his father, King Charles III, in "Spare."

Roberts theorized that Markle's memoir might be even more potent than any revelations from Prince Harry. She explained, "I see more danger coming from her autobiography, her truth, which would be Oprah on steroids."

Coy, meanwhile, reacted to claims that the Sussexes might refrain from creating content pertaining to the royal family, as they have "nothing left to say."

"Every single time I thought that was the case I've been wrong," Coy admitted. "I felt that after Oprah, so I'm hesitant to say it again."

Yet, she proposed that Prince Harry may have exhausted his repertoire of royal family tales. "But I would say it does seem like he has said all that he has and the royal family probably feels the same, 'What else can he possibly say? He said so much.' So, maybe there's a little bit of reassurance for them in that. Surely it's all been said at this point," she suggested.

Last month, The Sun reported that the Sussexes would refrain from "royal-bashing" interviews, tell-all books, and documentaries as they have "nothing left to say."

However, Kinsey Schofield, a royal commentator and author, believes the Sussexes aren't finished yet. "'There is nothing left to say' is a factually inaccurate declaration," Schofield posited. "Prince Harry himself told The Telegraph that he held back revelations in 'Spare' to protect his father and brother. This portion of his interview was instantly interpreted as a potential threat that Harry could continue to spill the tea."
