Selena Gomez says her relationship with on/off boyfriend Justin Bieber is "crazy and intense".The 20-year-old singer has an on/off relationship with the 'Baby' hitmaker and while they haven't clarified the status of their love life, she admitted all the attention surrounding them hasn't made their time together easy.She told InStyle: "[It is] crazy and very intense. It's uncomfortable that everywhere I go, people know. I don't like that."I have to go through the emotions and feel it out. I'm doing my own thing, being with my friends, and he's doing very well too."The ballad 'Love Will Remember' on her new album 'Stars Dance' is about Justin and Selena thinks he will approve.She said: "That's the most personal track on the record for sure. I think it's a sweet way of releasing it. It's not an aggressive approach to what people are probably expecting. I'm sure he'll love it too."After Selena and Justin, 19, recently spent time together in Norway, her friends and family urged her to dump Justin for good.A source said: "We did everything we could to keep them apart but he was so persistent."It's really unhealthy they have such a turbulent relationship at such a young age. He leaves her in floods of tears constantly."She has had a really difficult year or so dealing with the tense, emotions that come with dating him. We thought she had finally broken free. But he has persuaded her to take him back again. There's not much we can do about it - but we are going to try."Another friend added: "She spent the last year of their relationship an emotional wreck. And we can see no end in sight to this."
