Heidi Klum celebrated her fifth wedding anniversary with husband Tom Kaulitz in St. Barts, where she felt 'free' going topless on the beach. The 51-year-old supermodel shared several Instagram posts, including videos of her running through the water in a thong bikini and a completely nude photo by an infinity pool. Klum, who embraces her European roots and comfort with nudity, emphasized that she finds such displays normal and non-offensive. Despite criticism over their 17-year age gap, Klum and Kaulitz enjoyed their romantic getaway, showcasing their affection publicly. Klum, a judge on 'America's Got Talent,' also mentioned her favorite contestant during a recent episode of the show.
