Proof That Weight Watchers Is Definitely Working for Oprah Winfrey

If witnessing Oprah Winfrey dominate television for decades has taught me anything, it's that she's not one to do something halfheartedly. When the mogul decided to commit herself to Weight Watchers in 2015, not only did she become a member, but she bought 10 percent of the company for $43.2 million. Now, she's promoting the diet regimen by revealing her own astounding weight loss.

At the premiere for the new OWN series Queen Sugar, Oprah flaunted her trim physique in a flattering LBD. Though Oprah kept quiet on exactly how much weight she's lost to date, she did express reaching a pretty hilarious milestone — one that involves her longtime boyfriend, Stedman Graham! She told People, "I would like him to pick me up and carry me to the pool. I've lost enough weight, he can pick me up and carry me to the pool. I can straddle him without breaking his back."

Look ahead for the latest pictures of Oprah's weight-loss journey.
