Heidi Klum Celebrates 52nd Birthday in Style With Beachside Bikini Pics

To mark her 52nd birth­day, Hei­di Klumditched 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.

Hei­di Klum’s birth­day was cel­e­brat­ed by the pool

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.
