To mark her 52nd birthday, Heidi Klum ditched the usual birthday dress and slipped into several string bikinis instead. From bold purple to soft blue and deep maroon, Heidi turned a regular day by the pool into a full-blown summer shoot.
She shared the sizzling moments on Instagram, flashing her toned figure and carefree energy to over 12 million followers. Each look, part of her campaign with Italian swimwear brand Calzedonia, captured a different mood: relaxed, radiant, and totally unbothered. One video ended with her walking away from the camera in a cheeky bikini. “Summer 2025,” she wrote in the caption. That’s how you make a statement.

While the photos made headlines, Heidi also gave fans a quiet peek into her birthday celebration. There was a cake with floral designs, a floating “Happy Birthday Heidi” balloon, and her husband, Tom Kaulitz, grilling while a band played nearby. Even their dogs got in on the fun, playing in the yard.
But all eyes were still on her bikinis. In an interview, she said going topless on vacation felt freeing and natural. “It’s no big deal,” she told Fox News Digital. It’s clear that for Heidi, birthdays are not about numbers; they’re about freedom, fun, and feeling good.
How does Heidi Klum maintain her glow at 52?
Klum’s fitness and lifestyle habits are part of what makes her glow at 52. She runs regularly, often along New York City’s West Side Highway. She’s also a fan of early-morning smoothies and makes them with her kids. “It started as a resolution,” she once shared, “but now it’s a habit.” She believes in staying consistent, whether it’s jumping on a trampoline with her kids or squeezing in hotel-room workouts during travel.
Outside of her birthday post, Heidi’s also busy with work. She’s returning as host of Project Runway, which is moving to Freeform. She’s also a judge on America’s Got Talent.
