"I'm trying on this super cute bikini and I was reminded of how far I've come when it comes to self-acceptance. Tomorrow I turn 61. I know this sounds crazy to some, but 40 years ago, when I was 21 and at the peak of my career as a supermodel, that's when I felt the most insecure," she stated. "I never looked good enough. Of course, that partly happened because my self-esteem was completely tied to my appearance," she said. She also wrote about how she put on the bikini, flexed her muscles, and showed her cellulite-covered butt, not necessarily to look her best, but to feel her best in her 60s. "Actually, who am I kidding? I've ramped up my workout 10 times more because I want to look the best I can this summer, but not necessarily in a bikini, rather in a wedding dress," she shared.
