Selena Gomez was “afraid of thunderstorms” as a child.

The 30-year-old pop star grew up in Texas and Selena revealed she lived in fear of thunderstorms and tornadoes.

In a clip from her new documentary My Mind and Me, which was published by Vanity Fair magazine, Selena says, “When I was a kid, I was afraid of thunderstorms. I grew up in Texas and I was so scared that lightning and thunder would mean a tornado was coming.”

Selena was eventually able to overcome her fears after reading about thunderstorms and their causes.

Selena’s mom bought her a few books on the subject, and it helped ease her worries.

The brunette beauty explains: “[She] basically said, “The more you learn about it, the less you fear it.” And that really helped.”

Selena recently admitted she’s “nervous” about sharing her “struggles” in her new documentary.

The “Lose You to Love Me” hitmaker admitted to having mixed feelings about the project.

She explained: “As nervous as I am to put something so personal out there, I know deep down that now is the time.

“I hope that by sharing my experiences and struggles, it will help people feel inspired to share their stories. And to have hope that everything can and will be better.”

The documentary explores the pop star’s mental health journey, with Selena admitting that the project “took on a life of its own”.

She said: “There was never such an elaborate plan where we thought we were going to capture these very personal parts of my life. It just evolved from there.”

Selena teamed up with filmmaker Alec Keshishian to make the documentary, and she enjoyed her experience working with Alec, who is best known for his 1991 Madonna documentary.

Selena said: “He is very kind and caring and I trust him completely. Most of the time I forgot that he was even around. Sometimes he just used the iPhone that was hiding in the corner.”
