"Many models are in long-term relationships for stability," the 26-year-old spilled. "Admittedly, not always with great men, but it gives them something to come home to, something grounding. That's how I see my relationship."
The blonde beauty - who was almost unrecognisable in her glossy cover shoot - explained she needed lots of cuddles on the couch after she was trolled on social media."I read everything on the internet and I got destroyed by it. I panicked. I was unhappy because I was nervous and insecure, so I cut it off. Today I am in a healthier and happier place."
She also made sure to address her chilly reputation. "I can see why people think models come across as a little cold. When you start out you're so young and you don't have a voice. Everyone just tells you what to do and you can end up abroad in the middle of nowhere, with no one speaking English.
"It is very lonely... You develop a thick skin to protect yourself. Now I am 26, when I come on a set, I can say what I think and my opinions are noted. I've grafted to be here."
