Biel and her husband, Justin Timberlake, became first-time parents when the actress brought the couple's baby boy, Silas, into the world last April. Prior to this, Biel's stylist Estee Stanley helped her out to make sure she was comfortable in what she was wearing. In a post from Life & Style last Friday, Stanley mentioned that Biel wasn't too picky about what was thrown on her.

"I don't know too many girls that like to get dressed when they're pregnant," the clothing expert said. "It's not the most fun thing watching your body change like that, but [Biel] is such a beautiful earth mother. So anything that we put on her, she was happy, as long as it wasn't constricting or she couldn't breathe. Everything for her was more like flowy things, or things that weren't constricting."

Stanley also recalled that Biel wasn't too confident when she was making red carpet appearances, but that changed overtime.

"When I first started working with her, she showed up in these jean shorts that had wet suit material attached as legs," the stylist said. "So she showed up in those and I was like 'uh oh,' but after years of working with clients, and especially someone like her who wasn't into fashion even at all, her confidence transformation was incredible. She turned into a different person."
