The billionaire media mogul is taking a 10% stake in the company, which boasts it has helped A-listers like Jennifer Hudson and Jessica Simpson slim down, for about $43.2 million.
Weight Watchers can now use Oprah Winfrey’s name, image, likeness and endorsement for its programs, products and services — subject to her approval.
“Weight Watchers has given me the tools to begin to make the lasting shift that I and so many of us who are struggling with weight have longed for," Winfrey said in a statement. "I believe in the program so much I decided to invest in the company and partner in its evolution."
Winfrey, 61, has been open about her struggles with weight loss for years, but her decision to join Weight Watchers comes not long after her best friend, “CBS This Morning” anchor Gayle King, shared her success story using a portion-controlled, points-based system.
“Watching the scale go down,” King captioned a celebratory photo of herself on a scale.
“You know it’s a brand new day when the weight that use to send you to the fetal position now has you doing the happy dance,” she captioned another photo, sharing she's shed almost 10 pounds since joining the program last month.
Winfrey — who is worth about $3 billion — sent Weight Watchers’ shares soaring more than 75% by 10 a.m. Monday morning.
