Actor Impossible! Leah Remini Blasts Tom Cruise For Hissy Fits

Scientology "god" Tom Cruise screamed at his assistants on one occasion when he couldn't find the ingredients to make cookies — and once threw a hissy fit when he was given tea in a chipped mug, according to Leah Remini's scathing new book, Troublemaker.

"Do you know who gets served with a mug that's chipped?" Cruise screamed, according to the book. "F*****g DBs!" — a reference to the Scientology term "Degraded Being."

RadarOnline.com can reveal that Remini also rips Kirstie Alley, who spearheaded a special Scientology mission to New Orleans after 2005's Hurricane Katrina. Leah gave $50,000 toward supplies.

But Remini said when she demanded some proof that actual supplies — and not just Scientology booklets — were being handed out to survivors, she was "given the runaround."

After leaving Scientology, vengeful Alley tried to keep her off Dancing with the Stars.

A rep for Alley told RadarOnline.com Remini's claims are "false and easily proven."
