In a new interview with E!’s Daily Pop, the 49-year-old supermodel jokingly credited her ever-youthful look to her husband, Tom Kaulitz, who is 17 years her junior. “I suck his young blood, is what I’m doing,” the America’s Got Talent judge quipped. “Like a vampire.” But on a more serious note, Klum told Daily Pop that she’s always sure to wear sunscreen, although her main method for staying young is to enjoy every moment in her adventurous relationship with the musician. “I feel like we’re never gonna be as young as we are right now, so we might as well live right now,” she explained. “I love to live right now, and for me, that is sun and having fun and, you know, just wear sunscreen.” Her plan to seize every day seems to be working, as Klum said her three years married to Kaulitz have flashed before her eyes. “It flew by, but it feels like a lifetime already,” she stated. “I just know him so well. We just gel really well.” “I just feel like, ‘Finally I found the one,’” she added. “So far so good. I hope it stays that way.” The gorgeous couple recently took a 2-week trip to Austria to focus on wellness, where they both learned “how to be better with our bodies,” Klum also told the outlet.
