Expecting mothers and new moms might wanna check this one out.

Former Destiny's Child and soon-to-be new mom Kelly Rowland has added a new beauty secret to her R&B repetoire.

Rowland also mistakenly revealed the sex of her baby too! "We're very excited," Kelly said to FOX411. "So far, everything has been good. I just feel like the baby is already rotten-like literally, my Caress family has gotten him all of his little bathing stuff, his toys-it's just so cool."

When Kelly realized she let the cat out of the bag, she sighed heavily and laughed, "It, it's...aw, f--k it! It's a boy. It's a boy!"

Even though early in her pregnancy, Rowland already has a post baby body plan. The singer was recently spotted purchasing Belly Bandit shapewear while shopping in Sherman Oaks. Consider it the corset training for women after giving birth.

The Original Belly Bandit is a worldwide belly wrap sensation, so no wonder Kelly got her hands on one. For $50, this band creates compression around the midsection and tummy, helping shrink the belly, assisting with healing, reducing inflammation and aiding in stretch mark prevention and reduction.

Other women also adore the new Bamboo Belly Bandit. As an environmentally friendly belly wrap, it will tighten and shrink your tummy post pregnancy, even after a c-section for $70. This seamless wrap hugs your body for a comfortable fit and has Velcro to help you size down.

Despite opting to get a Belly Bandit on her own, Rowland is still seeking tips on motherhood. "All my girls have given me advice," she said.

"I have a wonderful crew of girlfriends. As women, we're powerful, and women have been so supportive. They always have such nice things to say, whether it's 'Oh my gosh, you look so nice,' or giving me different advice, and that feels good."
