Former Spice Girl and mom-of-three Mel B took to Instagram to share a pic of herself wearing a gold watch, a couple of bangle bracelets, and pretty much nothing else as she posed in front of a mirror with her arms crossed over her chest, in an effort to promote body positivity. “As a woman I embrace my flaws and I'm comfortable in my own skin,” she wrote in the caption. “Might as well I’m gonna be in it for the rest of my life. I’m the kinda girl that has absolutely no desire to fit in. Ladies we gotta love the skin we are in.”

YASSSS! Even though we have no idea what flaws the X Factor judge could possibly be referring to, we are totally feeling the girl power behind what could have been just another indulgent naked selfie. Zig-a-zag-amazing, Mel!

Blac Chyna

Black Chyna—who is engaged to Rob Kardarshian and expecting his baby any minute—is definitely keeping up with her fiancé’s sister Kim. The 28-year-old posed pregnant and completely au natural with her blooming tattooed belly on full display for the September 2016 issue of Paper magazine–the same publication that “broke the Internet” after featuring Kim’s bare, champagne-covered bottom on it’s cover. Chyna posted a stunning outtake from the shoot over on Instagram, along with the caption. “Blac Chyna, mogul, entrepreneur, a mother and a bad*ss bitch.” Modesty definitely does not run in this family—and why should it when you look this amazing? 

Alanis Morissette

It’s like rain on your wedding day…. or, you know, going skinny-dipping when you’re pregnant. While expecting her second child with husbandMario “Souleye” Treadway, singer-songwriter Alanis MorissetteInstagrammed the most amazing picture of herself completely naked and submerged in water. Her hands are demurely covering her chest, but otherwise, the rocker’s stunning pregnant body is on full display as she serenely floats underwater like some kind of mermaid goddess. And she punctuated the picture with a pretty awesome quote from her 5-year-old son, Ever, too. “You have to be extra gentle around ladies because they are the most helpful people in the world ’cause they make persons.” #truth

Tess Holliday

Tess Holliday is anything but shy about showing off her famous figure. While expecting her second child, with fiancé Nick Holliday, the plus-size model stripped down for an awesome naked baby-bump selfie to hit back at all the critics who claimed they couldn’t tell she’s pregnant. “I will continue to live unapologetically, to thrive in this body, prove the naysayers wrong & laugh at the ignorance,” she captioned the stunning shot, adding the hashtags #babyhollidayontheway #37weeks #effyourbeautystandards #plussizepregnancy. Way to go, Tess! Haters gonna hate, so you just keep doing you.
