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.

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."
