Jeff Bezos pens cheeky Amazon review of fiancée Lauren Sanchez's new book

Jeff Bezos appeared to write a gushing - and hilarious - review of fiancée Lauren Sanchez 's new children's book on Amazon.

Former TV star Lauren, 54, officially became an author earlier this month when she released her first kid's title, The Fly Who Flew to Space.

The book - which follows 'an adorable fly named Flynn as they follow their dreams of becoming an astronaut right onto a rocket ship' - has since received a slew of positive ratings, including one that appears to be posted by 60-year-old Jeff.

On the book's Amazon listing, an account bearing the name of Jeff Bezos left a review fiercely praising the book.

Jeff gave the tome the maximum rating of five stars, but said he would have given it 'six' if he could.

He comically described it as 'the best children's book his fiancée had ever written,' something that was not hard for her to achieve as this is her first and only children's book.

While there's no way to tell if the account is indeed Jeff's, sources confirmed to USA Today that it is.

DailyMail.com has reached out to Amazon for comment.

The account's profile picture is an old snap of Jeff, and it has a total of eight other reviews, most of which were made in the early 2000s.

One of the reviews, posted in 2006, was for a carton of milk, and it was titled, 'Long time fan.'

'I love milk so much that I've been drinking it since the day I was born,' it read. 'I don't think it was Tuscan though.'

He also praised Aunt Lizzie's Cheese Straws, describing the 'low-carb' snack as 'delicate' and 'amazing.'

'If you're doing a low-carb diet or looking for snack foods that won't trigger a glycemic reaction, try these amazing cheese snacks,' he wrote.

'They are very delicate and pastry-like, crumbling in your mouth. Very savory - no sweetness.

'Aunt Lizzie is on to something, and these are a no-compromise low-carb snack.'

The review, posted in 2003, was titled, 'My mouth is watering as I write this.'

In addition, the account left a gushing review of some 'ridiculously good cookies' in 2003.

They are no longer on the Amazon site so it's unclear what brand created them.

'This is an assortment of carefully wrapped cookies. They claim to ship only hours after the baking is done, and the taste would certainly indicate that that's true,' he said.

'I'm not exactly sure how many different cookie types there are in the box since I (and my co-workers) started eating before I started counting.

'But somewhere around eight or more different types. The snickerdoodles were the best I've ever had. Ridiculously good cookies.'

Jeff also left five-star reviews for the books Down and Out in the Magic Kingdom by Cory Doctorow, George Dyson's Project Orion: The True Story of the Atomic Spaceship, and The Proving Ground: The Inside Story of the 1998 Sydney to Hobart Race, written by G. Bruce Knecht.

He also reviewed the film Life is Beautiful and a pair of $1,179 binoculars made by Canon.

'The problem with high power binoculars is that humans can't hold them steady, and that jitter makes it impossible to really look at something without a tripod,' he wrote for the latter.

'The image stabilization in this pair solves that problem and holds things rock steady.

'This is an expensive product that clearly distinguishes itself, and one of those products that technology makes seem a little magic.'

He added that he did have 'two small complaints,' which included the lack of a pre-installed neck strap and a high-quality lens cap.

Many of Lauren's other friends and loved ones made sure to leave positive reviews for her book on Amazon.

Her close pal, Laura Wasserman, described it as a 'new classic to add to your gift list,' while her sister, Elena S Blair, said it was 'a must for little ones of all ages.'

During an appearance on Good Morning America earlier this month, Lauren explained that she was inspired to write the book after suffering from undiagnosed dyslexia throughout her childhood.

She also revealed that some proceeds from the book would go to the International Dyslexia Association, which helps diagnose children at a younger age.

It was revealed earlier this week that Lauren was being sued by her former yoga instructor , Alanna Zabel, for allegedly plagiarizing with the book.

In the lawsuit, obtained by TMZ , Alanna claimed that Lauren's book substantially ripped off her 2022 children's book Dharma Kitty Goes To Mars.

She claimed to have contacted Lauren in 2022 to pitch a children's book concept about a cat who flies to Mars.

She also said she sent the former journalist - who she taught from 2007 until 2010 - two cease-and-desist letters ahead of her book's publication, and alleged in the lawsuit that the theft was related to Lauren's 'continual and outrageous acts of jealousy' over the years.
