Bella Thorne credits her sister and an ex for making her feel confident enough to start singing again.

The Blended star recently returned to music after a three-year break by releasing her collaboration, Just Call, with Prince Fox earlier this month (Jul17). Thorne admits she has never felt comfortable singing and had no interest in making music.

"I've always been super uncomfortable with my voice and it just took me a long while to like music, like the music industry," she tells Just Jared. "I was never really great at it."

However, her sister and her boyfriend have recently become DJs and Bella felt it was time to start singing again.

"I was like, 'Do I really want to do this?' And then I started getting back into music because my sister (Dani) and her boyfriend Justin, they're DJs - and they just got into that - so we were kind of all stepping in together around the same time with music," she says.

"My ex sings and plays instruments and made me feel really comfortable about my voice and all of this together just kind of pushed me to get back in," she adds.
