Happy Birthday Ingrid Seynhaeve. The Belgium native, who turns 40 today, appeared in the 1996 Swimsuit issue and produced one of the most unique photos SI has ever published (above). She got her start after winning a worldwide modeling contest in her native country and has been in the industry ever since. In addition to SI, Ingrid has posed for Guess, Ralph Lauren, Sake and Victoria's Secret. She's also a bit of a daredevil and counts snowboarding, sky diving and scuba diving as her favorite activities. In honor of Ingrid's milestone birthday, we present this collection of her best swimsuit photos.
