After ABC teased the interview with several clips, Leah Remini finally appeared in the full 20/20 interview with Dan Harris, during which she dropped several major bombshells about Scientology.

Remini quit the church in 2013 and has since been publicly critical about it, but her assertions were nothing compared to what she revealed on the special that aired Friday night.

Ahead of the release of her memoir Troublemaker: Surviving Hollywood and Scientology, Remini told Harris about the "crazy sh-t" she experienced during her decades within the religious organization. She even revealed she spent over $2.5 million on behalf of the church.

Remini really went into detail about the role Cruise played in her eventually quitting the church after attending his wedding to Katie Holmes in Italy.

She said the church invited her friend, Jennifer Lopez, and her then-husband Marc Anthony to the “wedding of the century,” which she said was "on Tom's behalf.” That’s when things started to get strange, People reports.

They largely kept Lopez and Anthony away from Remini and her husband, Angelo Pagan, she claimed. “They were trying to extract me," she said. "I can only assume because they wanted to make Jennifer a Scientologist. Maybe I was barring that road for them."

She then got written up by several members of the church for “ruining” the wedding for being rude and loud. She said they claimed she "basically destroyed the wedding” and she subsequently reprimanded for it. Holmes herself even wrote a “Knowledge Report” against her for it.

When asked to comment on it, Holmes said, "I regret having upset Leah in the past, and wish her only the best in the future."
