Tina Fey is a real weight watcher.

The “30 Rock” alum sat down with Oprah Winfrey in St. Paul, Minnesota, on Sunday, on her “2020 Vision: Your Life In Focus” tour.

Fey revealed that she recently lost 30 pounds on a WW dieting plan.

“I was in Chicago, and really enjoyed the food… and the big coats,” she joked.

Watching her weight doesn’t mean Fey completely avoids sweets, though, offering up her recipe for a banana split alternative.

“I take a banana and strawberry, and put frozen cool whip on it with a chocolate drizzle, and tell myself it’s a banana split,” she said.

The 49-year-old also talked getting more introspective as she reaches a new stage in her life.

“I feel like I am at an age where all the things I’ve ever thought I wanted to do, I did them. I always wanted to work at ‘Saturday Night Live’, I always wanted to have a show, I always wanted to have children…” Fey said. “And I did that. So I feel like I’m trying to be quiet, and take things in. And listen. I’m waiting for something inside me to tell me what the next thing is I want to do.”
