Paulina Porizkova Is 'Baring It All' To Promote Her New Book 'No Filter'

Model Paulina Porizkova is not holding anything back in her latest social media snap.

Her upcoming book, "No Filter: The Good The Bad, and The Beautiful," is a collection of essays that give fans an intimate look at her thoughts on grieving, depression, beauty, grief, and aging in the public eye.

On Friday, the 57-year-old Sports Illustrated Swimsuit cover model took to Instagram to share a topless snap to promote her upcoming memoir.

On Friday, the Czech-born model took to Instagram to share a no-filter photo of her posing topless in a dimly lit room. Her long blonde hair falls in loose waves around her shoulders as she clutches an open copy of her new book to her chest.

“Yes, I’m baring it all. No filters,” Paulina wrote in the caption. “This collection of essays contains things I want to share, things I have thought about, things that hold me back, and things that propel me forward. It is all of me. For all of you.”

“I have expressed before how much your support means to me- and I’ll keep thanking you. Each and everyone of you,” she continued. “This book was written because of your support. I’ll have some fun announcements coming up, and for more information click link in bio to see what’s going on with the book.”

Actress Selma Blair – who recently made headlines for dealing with her multiple sclerosis during “Dancing With The Stars” - commented, “Excellent book. Oh wow. So proud. So loving you.” Paulina replied, "Likewise I’m so so proud of YOU my beautiful friend!”

Fitness trainer Ashley Borden added, “Good Lord ? ?.” Although Paulina responded with a laughing face emoji, Ashley replied, “ummm I’m not laughing ???❤️.” Singer Natasha Jane Julian also couldn’t help but gush over her sultry snap, commenting, “Amazing picture!! ? just stunning . Congratulations on the book. Can’t wait to read !”

Other fans showered her with praise as well. “You are an amazing example of a strong woman..., rooted in her power .. without succumbing to the restrictions and demands society puts on us ... I love you ❤️,” one fan commented. Paulina replied with a prayer-hands and red heart emoji.

“You are so beautiful inside and out! Congratulations on the book!!” another fan commented. “Neither your beautiful body nor your beautiful mind need any filtering. Such a complex desirable woman,” another follower wrote. “Oh I want to read! U are beautiful ? love how you share your struggles and triumphs,” another fan chimed in.

In another Instagram post shared on Monday, Paulina confirmed that fans will get to listen to an audio version of her upcoming collection of essays. “Here I am recording my book for the audio version of my book, for those of you who prefer to listen,” she wrote in the caption, adding, “I know I love my books on tape when driving!”

“I was inexplicably nervous to record the audio- because I had never done anything like it before. Interviews and shows and movies- sure, but just reading out loud?” she asked. “But it turned out to be really fun. In fact, reading my book out loud with the intention it was written, felt fantastic.”

“I drank endless glasses of water to keep my mouth moisturized- (who knew?) and had to keep a pillow in front of my stomach because it turns out, when you’re in real silence your stomach does quite a bit of talking! (Who knew?),” she joked, offering a “Big thanks to @cdmstudios !”

“My book No Filter, the Good the Bad and the Beautiful , will available in bookstores November 15th- but available for pre-sales now , just click link in my bio!” she added. “That also has whatever upcoming appearances and the bookstores!”

The day after the book is released, on Wednesday, November 16, she'll make an appearance at the Barnes & Noble in Union Square for a conversation with Kerry Egan. On Friday, November 18,  she'll be at the “Books & Books + The Coral Gables Chamber of Commerce” and follow it up with another conversation on Saturday, November 19, at the Miami Book Fair in Miami Dade College for a conversation with Dani Shapiro.
