Heidi Klum, 53, was seen enjoying a family vacation in St. Barts, splashing in the waves in a thong bikini. The supermodel vacationed with her children and her dog, Fritz, whom she introduced on Instagram in April.

Klum was joined by her daughter Leni, 22, and Leni's boyfriend, hockey player Aris Rachevsky, also 22. Leni's beau was seen carrying her across the sand at one point. Klum's son Henry was also present for the outing.

During the beach day, Klum adjusted her bikini top while emerging from the sea. She was also seen wading in the shallows with Fritz before returning the dog to dry land. Klum's daughter Leni and Rachevsky were also seen interacting with the pup.

In recent weeks, Klum shared that her husband, Tom Kaulitz, encouraged her to gain weight, stating she appears better with a fuller figure. "My husband was the first one who pointed that out. He said, 'You should eat more; you would look better if you had more meat on your bones,'" Klum told Us Weekly. She added that she is not interested in weight-loss drugs, noting she has gained weight over the years and believes people look better with age.

Klum and Kaulitz, who married in 2019, sometimes face challenges due to their busy schedules. Klum mentioned that her filming schedule in New York and Kaulitz's tours can lead to time apart. However, she plans to accompany him on tour later this year.

Klum's eldest child is also a fashion model who has walked runways and starred in major fashion campaigns including Dior and Fila

Klum also spoke about a worm and parasite cleanse she and Kaulitz underwent. She admitted she was unsure if the process, which involved herbal supplements, had any effect but said it "just felt good."
