The supermodel is unfazed by the 17-year age gap with her new boyfriend.
In a recent interview with InStyle, Heidi Klum, 45, opened up about her relationship with Tom Kaulitz, 28.
Heidi, who was the first German model to become a Victoria's Secret Angel, said she doesn't care what people think about the 17-year age gap between her and boyfriend Tom.

She told the magazine: "My boyfriend is many years younger than me, and lots of people are questioning that and asking about it."
"That's really the only time when age seems to be shoved in my face and I have to give an answer for it."
Heidi added: "I don't really think about it that much otherwise. You have to just live a happy life without worrying too much about what people think because worrying is only going to give you more wrinkles."
For her, age is just a number.
"I don't really think about getting older that much," she said. "I mean, [I] know it's happening to me; it's happening to all of us. But it's not like I wake up in the morning, look in the mirror, and say, ‘Oh my God, oh my God.' Lately, I'm being reminded more about my age by people other than myself."
Heidi said she still used to deal with the media attention.
"Sometimes they'll compare a photo of me from 10 years ago, right after I had a baby, with a photo of me right now, and say, ‘Oh, she was curvier then, or her boobs were so much bigger,'" she said. "Yeah, they were so much bigger because I was breastfeeding! And I probably really needed to pump right then. You just have to come to terms with it."
Rumors about her relationship with Tom, from Leipzig, Germany, began spreading in March after they were seen kissing on the set of America's Got Talent. Since 2013, she has been a judge on the hit NBC reality show.
As reported by Instyle, Heidi and Tom made their red carpet debut in May at the Cannes Film Festival amfAR Gala.
They've also shared their relationship with their followers on social media.
