Serena Williams is getting through her pregnancy with a little help from her friends.
Williams, 35, is expecting her first child with fiance Alexis Ohanian, and on Wednesday revealed that she's turned her friend Kelly Rowland's book, Whoa Baby! A Guide for New Moms Who Feel Overwhelmed and Freaked Out (and Wonder What the #*$& Just Happened), into her own personal study guide.
"It's just raw," Williams said, as part of an interview on behalf of her sponsor, Tempur-Pedic. "It's everything that no one wants to tell you. I highlight things in it. I study it. It's been really, really, good for me."
In an exclusive interview with ET about the book in April, Rowland said that all moms "love hard...it doesn't matter if you're a celebrity mom or a mom that is a stay-at-home mom...we're all in this together."
