As Beyoncé continued serving looks while she is pregnant with twins, she stepped out in LA to celebrate motherhood and the latest achievement of her longtime friend, Kelly Rowland.

With Michelle Williams also joining in on the festivities, much to the delight of fans, the occasion also doubled as an unofficial Destiny's Child reunion.

In addition to building her own legacy in the entertainment industry, Rowland can now add proud author to her impressive résumé.

The singer and media personality has officially penned her first book, Woah, Baby!, a guide for new moms as told from the witty and extremely honest perspective of the singer, who became a mom for the first time with the birth of her son Titan.

The book's official title, Whoa, Baby!: A Guide for New Moms Who Feel Overwhelmed and Freaked Out (and Wonder What the #*$& Just Happened), accurately sums up how many women feel when first diving into motherhood. 

For the book, Rowland recruited OB/GYN Dr. Tristan Emily Bickman to offer medical insight to all of her questions--including questions such as "Will I ever sleep again?" and "Are my boobs always going to look like this?"--with Rowland putting as much personality into this book as she did helpful information.

Rowland's new book is available for sale here.
