In 2012, after Oscar-winning actress Octavia Spencer won her big award for the movie "The Help," she was courted by weight-loss company Sensa. In five months, she lost 20 pounds.

The weight loss company enjoyed the use of her famous face and her public endorsement. Spencer, as mentioned, lost weight and admitted to feeling better. What could possibly go wrong?

As it turns out, quite a lot. Yesterday, the actress filed a lawsuit at L.A. Superior Court alleging "breach-of-contract and fraud," The Hollywood Reporter exclusively reports.

Sensa, for those unfamiliar with the product, is "a doctor formulated weight loss system you sprinkle on your food to help you eat less and feel full faster" -- according to the company's website. As documents obtained by THR show, Spencer signed a $1.25 million contract with Sensa, but had certain stipulations: She refused to do tabloid ads, refused to partake in "before and after" photos, and she insisted on transparency with her fans by tagging all sponsored tweets with the required #spon hashtag.

The latter, apparently, made the people at Sensa very unhappy.

In the lawsuit, Spencer claims the company is blaming her "for the failed advertising campaign" and is trying to back out of paying her $700,000.

Just last April, Spencer spoke to HuffPost and had nothing but great things to say about her newly-adopted healthy lifestyle. "I can't tell you how thrilled I am that [Sensa is] a part of my life because weight loss is hard," she said. "Twenty pounds is a lot of weight. And so getting out of your head and being consistent and using a product that definitely enhances your life is … I'm screaming it from the rooftops because I know how hard it is and it's just been amazing for me. Amazing."
