Sports Illustrated surprised Musk with the news that she was not just going to be in the issue but was going to be one of the cover stars. A video on the SI website shows the big reveal and Musk seeing herself on the cover of the magazine for the first time. In an interview with Sports Illustrated during her photoshoot in Belize, she said, “If I thought I could be a swimsuit model for Sports Illustrated, people would have laughed me away as a crazy lady. And now, here I am.” Musk’s fellow cover stars are reality star Kim Kardashian, singer Ciara, and model and musician Yumi Nu. Speaking to People about being on Sports Illustrated, Musk explained that she hopes posing for the issue helps other women feel more comfortable in swimwear, too. “My first reaction was, I could never dream up something like that because why would anyone have a 74-year-old on their cover, especially in a swimsuit,” she said. “I do think it’s going to make women feel more comfortable in their 70s when they swim, as well as women in their 20s and 30s.” Musk continued, “When women go to the beach, we’re kind of shy about our bodies, but men will walk around, looking terrible, and they don’t care. I think we have to not care that much!” For more celebrity news delivered right to your inbox, sign up for our daily newsletter. Musk also talked to People about how she’s regarded differently in her 70s and how women shouldn’t have to wait that long to be treated respectfully.ae0fcc31ae342fd3a1346ebb1f342fcb “I went through different stages of my life where I was rejected, insulted, disappointed and it just takes away your confidence,” she said. “Then you just have to get over it. So here, I’m 74, I’m the happiest I’ve ever been, and I don’t care, and nobody’s insulting me because—you don’t want to insult a grandmother. The point is, people are really good to me at this stage, but why should it take so long?” Providing representation for mature women is nothing new for Musk. In recent years, she has modeled for various editions of Vogue, in advertisements, and on the runaway, and she was in Beyoncé’s music video for the song “Haunted.” In 2017, she became the oldest CoverGirl spokesperson at age 69. “I’m turning 70 in April of next year. I think that women will be really inspired to see that even at 69 you can get a beauty campaign,” she told The New York Times at the time. “Aging has been good for me. You develop confidence, you’re able to handle the knocks a little easier. I model for my age. I’m not trying to hide it and say I’m 50. I’m so proud that I’m going be 70.” READ THIS NEXT: See ’80s Supermodel Kathy Ireland Now at 58.
