Chelsea Clinton pens children's picture book

Usually I am not exactly hot on the trail of celebrity picture books.  Over the years, I've found most celebrities seem to believe writing for children is easy, and we all know that's just not true.
But, now and then I get excited for a new title coming out, and my hopes are up for Chelsea Clinton's new book, She Persisted with illustrator Alexandra Boiger (I LOVED While Mama Had a Quick Little Chat.)  At any rate, this cover looks fabulous.

So far, no authoritative reviews, but I'm crossing my fingers for something great.  What is your favorite celebrity written children's book?
