Even while enjoying her tropical vacation, the model-turned-businesswoman undertook some product testing for her new eponymous swim line. In an epic landscape shot that redefines vacation goals—lush palm trees line a pool deck that borders a beach boasting bright blue tropical waters just beyond—Klum is seen swimming in the pool in a hot pink bikini. "Testdriving my new HEIDI KLUM SWIM line," the 43-year-old stunner captioned the post, adding a fitting pink bikini emoji at the end. In another post, she shared a glimpse of the tag of her new line poking out above the sand. The Project Runway host has given us an enviable lineup of vacation photos in which it appears she's spent most of her time in a bikini. On Friday, the supermodel sported bikini bottoms sans top, flaunting her impeccable physique while standing on her villa's balcony with her back to the camera. In two more posts, Klum is captured underwater, showing off her gorgeous necklace while covering up her bare top.
