Heidi Klum has revealed that she saved her son Henry and two nannies from being swept away by a large riptide, during their Easter vacation in Oahu, Hawaii. The 39-year-old actress told Entertainment Tonight that her family got pulled into the ocean by a big wave and she as a mother was very scared for her 7-year-old child and everyone else in the water. Klum said that Henry is a strong swimmer and was able to swim back to land. Klum added that she and her boyfriend Martin Kirsten, who also sprang to action, were able to save everyone. In photos posted on the ET Web site, the supermodel can be seen tugging her son and a nanny to shore as large waves crash down. Kirsten is also seen on his hands and knees, catching his breath after surfacing from the water.
