The "Married at First Sight" star, who has two children with her husband Doug Hehner, took to Instagram on Saturday to share a video of her proudly showing off her "mom body" with an inspiring message about body confidence during the summer months.
In the video, the 35-year-old walked along a dirt path wearing a black strappy bikini and brown sandals. She threw her hand to the sky and flashed a million-dollar smile at the camera. The video also featured on-screen text, saying "actual footage of me walking and not caring what anyone else thinks of what I look like in my swimsuit."
"This weekend marks the beginning of summer. We all have body hair, stretch marks, cellulite, and rolls ... Wear the suit and go enjoy yourself," she captioned the post.
Followers loved the inspirational post, praising Otis for her vulnerability and transparency.
"Thank you for showing us that it's OK and important to love our natural bodies," one follower commented. "Your bravery and body positive posts have inspired me to go out and get a new bikini!"
"Amen! We need to enjoy life without worrying what people think. Even if you had the "perfect" body people would still try to shame you or another woman," another fan wrote.
"You inspire me so much as I am at my heaviest after more than a decade of fertility treatments," someone else admitted. "You're helping me learn to love and not be afraid of my honest body."
The reality star, who also appeared on season 16 of "The Bachelor," has previously spoken about her body image issues. Earlier this month, Otis posted a video of herself tucking her stomach into her underwear followed by a compilation of hiking clips with her and her children.
Otis captioned the post, "TBH, lately I don't always like my new body after having babies and I rarely feel sexy with this 'mom pouch' that hangs out, but right now I feel pretty dang proud! I grew both of my babies in that 'mom pouch' and now I've carried both of 'em on my back hiking all across America."
She continued with a message to mothers, writing, "Mamas, we may be softer and squishier than we once were, but we are also stronger too. If you're feeling down, just tuck that mom pouch in, grab your babies (even if they're big now) and get out of the house! Life's too short to let a mom pouch stop us from realizing our strength."
