During the interview, Julia revealed why she didn’t keep Justin Bieber‘s smash hit “Sorry” – which she co-penned – for herself.

“It just wasn’t my time,” Julia explained.

“I’m a very nervous person and I’ve never really been much of a confident person, and it took a song like ‘Issues’ for me to realize that it was something that I wanted and something that I suppressed because I’m so fearful of it.”
