NEW YORK (FOX 5 NY) - Unlike her signature product, Spanx, which keeps the silhouette looking smooth, Sara Blakely's new project is to encourage mothers to "let it all out."
"It's all about pregnancy. Celebrating the belly. Let it all hang out," said Blakely about her new book, 'The Belly Art Project.'
All proceeds go toward maternal health charities.
"You can support serious causes in a fun way," said Blakely.
The mother of four painted her belly like a watermelon, basketball, beach ball and Mister Potato Head. Had photos taken of herself and then encouraged other expecting mothers to do the same.
"I got the idea three days before delivering my son," said Blakely.
More than seven years later the book is now available.
Celebrity moms including Alyssa Milano, Kate Winslet and more than 200 other women are featured in the book.
Blakely is giving away 100 copies of 'The Belly Art Project' on her Instagram page.
