A fitness instructor is suing Lauren Sánchez for theft of ideas, theft of intellectual property and intentionally inflicted emotional distress.

Zabel’s self-published book, “ Dharma Kitty Goes to Mars ” — which came out in March of last year and is sold, ironically, on Amazon — is a tale of a science student’s pet cat that falls asleep on a space shuttle and wakes up on a different planet.

Lauren Sánchez's new children's book is already a bestseller. But one particular Amazon review is getting noticed.

In the post, she also shared a photo of old school yearbook portraits and added in her caption, "Even one of my old teachers showed up and brought a yearbook. 😮”

Jeff Bezos has left a glowing Amazon review for the children’s book, The Fly who Flew to Space, written by his fiancee, Lauren Sanchez. Published on September 10, the illustrated book follows a fly named Flynn who pursues her dream of becoming an astronaut and ends up travelling to space in a rocketship.
