Kloss, who has been dating Joshua Kushner (brother of Jared Kushner) since 2012, reveals the secret to staying in love, “It’s not like I’ve ever wanted to be so secretive about my private life, Carolina Herrera always says, ‘A woman who’s an open book is boring.’”

She continued, “There’s no mystery anymore. I know in my life what really matters to me. I’m not trying to hide that from the world; I just really like having a more private private life. I’ve got nothing to hide, though!”

But aside from her ongoing and successful connection with Kushner, the former Victoria’s Secret model admits some of her friendships aren’t as lucky, “I’ve built really amazing friendships – some that last, some that don’t.”

But she’s thankful for the ones that stick, “A couple have become some of the most important relationships in my life, in particular, those I’ve been in the trenches with, such as Jourdan Dunn, Joan Smalls, Toni Garrn and Lily Aldridge. We started as girls and we’ve grown up together, and I know if I need anything, I can call them up and they will be there for me, just like my friends from kindergarten.”
