Former and future first lady Melania Trump has inked an eye-popping $40 million deal with Amazon to license a documentary on her life — with cameos from her husband, Donald, and son, Barron.

The documentary, directed by “Rush Hour” auteur Brett Ratner, is set to be released later this year — with one source close to the agreement suggesting it could spawn multiple projects.

The hefty price tag was first reported by Puck News and covers the rights to projects involving Mrs. Trump over the next four years.

Page Six has learned that Disney was also in the running and bid $14 million, only to be swamped by the internet giant.

Sources tell Page Six that the Amazon project is the latest sign that Melania has “gotten more comfortable” with opening herself to the public.

“She’s been very savvy about what she says … Melania has gotten more comfortable speaking in front of people and on TV,” the source said. “She is more confident and has taken full control of her public image which she knows is worth millions and she’s ready to be paid for the work she puts into the doc and revealing more about herself.”

Melania, 54, is the executive producer on the project after “insisting on control and approval” — with a little help from the president-elect.

“I’m also told her deal also gives her a piece of the backend, and that her husband helped structure the project,” the source said, referring to the practice of sharing in profits from a film once production costs have been recouped.

Amazon founder and executive chairman Jeff Bezos apparently “took a personal interest in the doc,” which our source said “has helped [him] get back on friendly terms [with Trump].”

The documentary promises an intimate look into the Slovenia-born first lady’s life — something that is expected to garner major interest due to her private nature, the source said.

“Melania has carefully limited and controlled both her image and access to her –– which has driven public interest,” this person explained. “By being removed from constant public exposure and being mysterious, she’s driven up both interest in her everyday life, and this has driven up her price.

“She’s private to the core but willing to put to use what she learned from her days as a model and as the wife of a master marketer. President Trump fully supports all of her projects.” 

Melania gave a written account of her life late last year with the release of her eponymous tome, “Melania,” which became a best-seller.

Ratner and a rep for Melania Trump did not immediately respond to a request for comment.
