Academy Award-nominated actress Queen Latifah has signed on to become the latest celebrity spokesperson for the Jenny Craig weight-loss chain.

“We officially confirm that Queen Latifah will join the Jenny Craig program in January,” Scott Parker, Jenny Craig’s vice president of marketing, tells PEOPLE Magazine. “We are thrilled to have Queen Latifah support our mission of improving health by taking her first step toward achieving a more healthful lifestyle.”

“Queen Latifah joins forces with Jenny Craig to communicate the importance of how small lifestyle changes, in the areas of diet and exercise, can have positive effects on overall health.”

But the thirty-seven year old plus-sized celeb isn’t in the market to lose weight:

She will have a “very different campaign, focused on a healthier lifestyle, not on getting onto a specific dress size.”
