Paulina Porizkova wows in striking bikini while celebrating her 61st birthday

Paulina Porizkova is celebrating her 61st birthday with a smile.

Earlier this week, the former supermodel uploaded a voice-over video of herself wearing a “super cute” red-and-white bikini while sharing that at the height of her career 40 years ago, she was the most insecure she’s ever been.

“I will be 61 tomorrow, and I understand that this might sound crazy to you, but 40 years ago, when I was 21 and when I was at the height of my career and supermodel-dom, that was when I felt the most insecure,” she said in the video.

Porizkova added, “I never seemed to be good enough” partly because her own sense of self-worth “was entirely tied to [her] looks.”

She also explained that her workout routine has been amplified as summer approaches, “not necessarily so I can look best in this bikini — but to feel my best in this sixth decade.”

To round out her video, Porizkova said, “You know, actually, who am I kidding? I kicked my workout up, like, 10 notches because I do want to look my best this summer, but not necessarily in a bikini — in a wedding dress.”

She closed out the video by blowing a kiss to the camera, flashing her engagement ring – she is currently engaged to producer Jeff Greenstein.
