Paulina Porizkova is showing off her playful side in an animal print bikini as she opens up about how she evaluates men as potential partners in her 50s. 

The supermodel took to Instagram on Monday to share a beachside snapshot of herself modeling a string bikini while sitting on a wooden bench at a tropical resort. 

She is makeup-free and smiling as the wind blows through her gray-streaked hair in the image, which was likely taken during her winter getaway last month. 

In the caption, Porizkova, 57, recalled what it was like to start dating again after she separated from her late husband, Ric Ocasek, who died three years ago.  

'Towards the last years of my marriage, I felt incredibly lonely,' she wrote. 'After we separated, I started to look at men again for the first time in 32 years as potential. And I remember thinking there was potential in virtually every man I met.'

Porizkova started thinking differently about how she views men after reading a science-fiction book that was published last year. 

'There is this great bit about evaluating men (or women) as possible partners through the eyes of a female pilot in the book "Termination Shock" by Neal Stephenson, where the fictional queen of the Netherlands (and a small plane pilot) whose husband had died, is looking for a new partner,' she explained. 

Porizkova went on to share a quote from the book: 'The tools she had used to evaluate boys as a teenager were no longer adequate to the task. She decided to consider the whole matter as she might evaluate the lift-to-drag ratio of an airplane wing.'

She noted that 'the "drag" ratio is the baggage the man comes with, while 'the "lift" is how he makes you feel.'

'The best is obviously low drag /high lift, and the only one you’d never consider is high drag/low lift,' she continued. 'For example, he lives on the opposite coast, which for me is medium drag.

'"He has young kids" would be high drag, as would "he’s not that interested." But I find him really sexy and interesting, which is high lift. "He’ll do, if nothing else shows up" — low lift. "He’s really nice" — medium lift.'

Porizkova noted that when she was 19, the year she met her husband, 'someone with a cool haircut or a record collection was enough to warrant my interest.'

'At 53, after spending 32 years with the same man, any man that exhibited interest in me was enough. These days, it’s all about medium drag/high lift,' she said, insisting that 'low drag men my age do not exist.'

The Sports Illustrated Swimsuit alum ended her post with a message to the men sliding into her DMs.  

'Gentlemen, thank you for the interest — but this is not [a] dating app, nor a hunt for medium drag/high lift men,' she concluded. 

Porizkova has been candid about her struggles with grief over the years following the death of her estranged husband. 

She and The Cars frontman were separated but still living together when he suddenly died of natural causes in their Manhattan townhouse on September 15, 2019, at the age of 75. 

The day after Ocasek died, she learned he had cut her out of his will just weeks before, claiming she had 'abandoned' him. He left her without any money to live off of, including her own earnings. 

Porizkova eventually reached a settlement with her late husband's estate in which she would receive one-third of Ocasek's assets, what was owed to her per New York state law. 

The author wrote about her life, career, and marriage in her new book of essays, 'No Filter: The Good, the Bad, and the Beautiful,' which was published in November.
