Lounging on a giant pizza floatie made perfectly for Instagram, Winter is seen rocking a teeny blue bikini throughout the series of sexy photos. In two of the pictures, the divisive star is seen from behind, showing off her perky derrière in the revealing two-piece. In the third photo of the series, Winter flaunts her toned abs as she lays with her eyes clothes and soaks up the sun.

Y'all I love you but PLEASE pay attention and post my REAL point from my @refinery29 interview!!! Not that I'm "defending living with my 29 year old boyfriend" or that I'm "firing back at Trump" because first of all I don't need to defend anything I'm super happy and in love, and I'm not firing at anyone just sharing an opinion after being ASKED! The point was to take back the beach and help people understand that the beach should be a safe space to go as you please and feel good about yourself no matter what! Makeup on, makeup off, heels, sandals, covered up, exposed, do you and feel HAPPY about who you are and YOUR choices, not the ones society wants us to choose. It's also HARD to be 100% confident- I'm still not- but I'm on a journey and I want other people to know they're not alone. We all struggle but through our struggle we get stronger and closer to our goals. Body positivity is important- not that I live with my boyfriend. Press- please read the article and take it for what it is- not what will give you more readers! Let's all be real and represent people how they want to be represented through what they actually say. Rant over. Love yourselves, love others, be yourselves, and be happy. Xo

Winter, who recently moved in with her boyfriend Levi Meaden, 29, is no stranger to showing skin on Instagram, though she clearly doesn't care what people think of her racy posts. Late last month, the star took to Instagram to fire back at her critics.

"Makeup on, makeup off, heels, sandals, covered up, exposed, do you and feel HAPPY about who you are and YOUR choices, not the ones society wants us to choose," she wrote in a lengthy caption under a photo of herself in a bathing suit. It's also HARD to be 100% confident -- I'm still not -- but I'm on a journey and I want other people to know they're not alone. We all struggle but through our struggle we get stronger and closer to our goals. Body positivity is important."

Mikey made me do it ... Miami nights 🙌🏻 1. This is my pre DWTS body🦄 2. I am not currently in Miami but am in NYC 3. I posted this knowing most of you would be judgmental and couldn't resist a chance to tear me down and I was right. 4. Go be offended at your own life. 5. I'm living my life to the fullest. ❤️
Just wanted to share that one of the reasons @eatingboys has inspired me so much is because of the way she mixes her humor and sexuality. I spent so many years loving my body but thinking it wasn't lovable by others- its sole purpose was to be fodder for jokes. I performed the insult so no one else could. I don't regret any of it- that's my art and that was my truth- but now, at age 31, having been through hell and back with my health and other people's perceptions of my physicality, I feel deeply comfortable with the idea that this pear-shaped pot of honey is equally good for making people laugh and laying out like a Suicide Girl circa 2004. Love it all.
