The 22-year-old singer is said to be worried her former boyfriend will use his heartbreak as inspiration for songs for his new album.

A source told HollywoodLife.com: "Selena is really worried that Justin is going to write about her in his new music. She's freaking out that he's going to diss her.

"They barely speak and she doubts he's going to let her listen to his music before it's released."

Meanwhile, Justin recently revealed he scrapped a whole album worth of music because his "whole direction" had changed since he penned those songs.

He said: "My whole direction has changed. What you are thinking about all the time is what you write, and now that I'm thinking about more positive things, it completely changes my music. I had to re-do my whole album. It was done but it didn't match up to where I am now and where my head's at.

"I want to tell my story, but I also want to give people hope. I lost hope for a while, I was in a dark place, but it's about getting out of that rut. It's about knowing there's sunshine on the other side."
