The 18-year-old went public with her relationship with Bieber, 17, in February and she said she's been shocked at their reaction.
She said to UK newspaper Daily Record: 'It's weird, it's just weird, but I don't pay attention to it, I just try to live my life as normal as possible.
'I just like to not focus on what the whole world is saying about me and just be happy with myself. I try to not read magazines or the internet but it's obviously unavoidable.
'I mean, it's everywhere, so there are moments where I read things that hurt my feelings. But not most of the time. I don't surround my life with magazines or the internet.'
