"I've struggled with comparison. I come from a world of modelling where it's really easy to compare myself to my own friends. You're just surrounded by a lot of beauty. I would say that every girl struggles with comparing themselves, whether it's on social media or (something else)," said Hailey, who is married to singer Justin Bieber.
She added: "There's always going to be other women or other girls that you feel insecure around, or that you compare yourself to: What if she's this and I'm not this? or What if I'm this and she's this? That is always happening no matter what, you know?"
