Oprah Winfrey welcomes Kate Hudson as WW ambassador

Dec. 17 (UPI) -- Oprah Winfrey is welcoming Kate Hudson as WW's newest brand ambassador.

The 64-year-old media mogul and WW part owner had a FaceTime call with Hudson after the 39-year-old actress joined WW, formerly known as Weight Watchers, as a rep.

Hudson shared a video of the conversation Sunday on Instagram and explained her motivation to join WW in the caption of the post.

"I've become an Ambassador for the WW family because it is the perfect community for people to live healthy their own way and I love sharing this knowledge with you all!" the star wrote.

"This is not a community for people who just want to lose weight, although leading a healthy lifestyle lends itself to such, this is a community about supporting each other through a life long journey of wellness," she said.

Hudson elaborated on her reasons while speaking to Winfrey.

"My 'why' is really my kids and my family and longevity and wanting to be here as long as I possibly can," she said. "It's really about the holistic approach to wellness."

Hudson is parent to two sons, 14-year-old Ryder with Chris Robinson and 7-year-old Bingham with Matt Bellamy, and welcomed a daughter, Rani Rose, with Danny Fujikawa in October. She told People her partnership with WW came at a great time.

"It came at a perfect time for me, because at this point after having three babies it's like sense memory. You want to start getting back into shape and to get strong again and focus on your own personal health," the actress said.

"It's hard when you have babies. Everyone comes before you, and you have to find that time to just focus on yourself," she added.

Hudson said in an Instagram post in November she hopes to lose 25 pounds before filming a new movie in the spring. She is slatd to appear in the movie Blood Moon with Zac Efron and Craig Robinson.
