Scientologywas once known for its array of celebrity church members.

“It’s part therapy, part religion, part UFO group,” Bromley toldCNN.

“It’s a mix of things that’s unlike any other religious group out there.”

For a while, Scientology seemed untouchable.

That was until a combination of scandals began to take the religion down.

She toldPeople, “I’m no longer practicing Scientology.

I’ve always been very open-minded, even since I was a child.

I was raised Catholic and Jewish.

I’ve prayed in churches, meditated in temples.

I’ve studied Chinese meridian theory.

A source toldUS Weekly, “These are tough times for the church.

Years ago, it [was] almost unheard of for a Hollywood star to openly walk away.

But the tidal wave of backlash generated by the likes of Leah and other whistleblowers has changed that.”

Whistleblowers like Remini and Prepon may have altered Scientology’s future success.
