'Kirstie Alley's Big Life' Trailer: Weight Loss Reality Show Preview

The trailer for Kirstie Alley's weight loss reality show is out.

"I was thin my whole life, til I gained 75 pounds," she says. "Then I lost 75 pounds, then I gained 75 pounds."

The point of the show is to lose it again, and cameras will be there every step of the way along with her kids and staff. She says she hopes that this is the last time she goes through the process and is looking forward to being the skinny booty call instead of the fat booty call.

"I think it's stupid to say you're full figured," she says. "Fuck you, you're fucking fat!"

'Kirstie Alley's Big Life' premieres March 21 at 10 on A&E.
