Where did Oprah Winfrey go?

While attending the premiere of OWN's new original drama series "Queen Sugar" in Los Angles on Monday, the talk show maven looked stunning and much thinner than perhaps we've ever seen her.

It's no coincidence that over a year ago she became the spokesperson and a shareholder in Weight Watchers.

In discussing her shrinking frame, Oprah joked that the real winner here is her longtime beau Stedman Graham.

"I would like him to pick me up and carry me to the pool," she joked to People magazine. "I've lost enough weight, he can pick me up and carry me to the pool. I can straddle him without breaking his back."

She wasn't afraid to show off her new body on Monday, rocking a dark, form-fitting dress with elbow-length sleeves.

Oprah hasn't said exactly how much weight she's lost so far, but she said in January that she was down 26 pounds.

"I don't feel like I'm on a diet that I'm ever going to go off again," she said of Weight Watchers. "I feel like I'll be counting points for the rest of my life."

She has previously said that her top weight was 237 pounds. During an annual health check-up in June, she revealed on Instagram that her cholesterol was 180 and her LDL cholesterol was 82. She said it was her "best health report card ever."

In a phone call with Weight Watchers members in late January, she said, "Every other time I've ever gone on a diet, I've gone on a diet and then gone off the diet, because I had gotten to the weight I'd wanted to be. The difference is, I've made the shift and this is the way I'm going to live for the rest of my life."

In a call two months later, she spoke about how the system works for her and how she manages questionable dietary choices.

"I basically eat exactly what I want and if I can't figure out what the points are…I just say I'm going to pass on that," she told members in March during another call. "If I can't begin to measure the points, I usually pass."
