Kourtney Kardashian – Born in 1979

Kourtney Kardashian turned heads on the beach in a neon yellow bikini that looked like it was made just for her. The world first fell in love with her on “Keeping Up With the Kardashians,” and she later starred in spin-offs like “Kourtney and Kim Take New York” and “Kourtney and Khloé Take Miami.”

She keeps her body beach-ready with a mix of strength training, pilates, and hiking, which she says keeps her feeling strong and energized. For food, Kourtney is all about clean eating—lots of organic veggies and lean meats, and she is known for loving keto and gluten-free options.
