Ariana Grande turned to Kabbalah after growing up Catholic because she couldn’t reconcile loving her gay brother Frankie Grande and belonging to a church that rejected his homosexuality.

Ariana Grande Left Catholic Church

Ariana discussed her decision to leave the Catholic church when she realized it did not accept Frankie's homosexuality in a recent interview with The Sunday Telegraph. “I was like, 'OK, that's not cool,' " the singer told the paper. "They were building a Kabbalah center in Florida so we both checked it out and really had a connection with it."

Kabbalah, a mystical offshoot of Judiasm ushered into the celebrity mainstream by pop icon Madonna, was a religion that both she and her brother could connect to. Years after she first checked it out, Ariana says she's still practicing. In fact, the pop star credits Kabbalah for her many success.

"[It] sort of stuck with me. And since then my life has unfolded in a really beautiful way, and I think that it has a lot to do with the tools I've learned through Kabbalah, I really do," she said. "You have to watch your intentions, make sure you're not giving in to your ego. You have to numb your reactive state. You have the power to change your reality."

Ariana added, "You have to take a second and breathe and reassess how you want to approach or react to a situation or approach an obstacle, or deal with a negative person in your space. That takes a lot of self-control and practice and, I guess, willpower."

Ariana's Gay Brother Frankie Grande

Before his sister made it big, Frankie had appeared on Broadway in Mamma Mia! in 2007. He recently made headlines on Big Brother until he was evicted from the house. Frankie's next gig is playing Franz in Broadway's Rock of Ages. He'll be performing on the stage at the Helen Hayes theater from Nov. 10 through Jan. 18.
