The Center for Science in the Public Interest is calling for Beyonce to walk away from her $50 million deal with Pepsi. According to Eurweb.com, the health group has said that the company is promoting an unhealthy drink in the midst of current health issues -- and says that Bey is glamorizing an unhealthy lifestyle.

The group said in a letter to Beyonce, "Your image is one of success, health, talent, fitness and glamour. But by lending your name and image to PepsiCo, you are associating those positive attributes with a product that is quite literally sickening Americans."

If Bey does go forward with the partnership, the health group said Beyonce should consider donating her salary to hospitals, diabetes organizations or other groups.

SIDE NOTE

This news comes days after reports say that PepsiCo added another artificial sweetener to its Diet Pepsi brand. The ingredient, acesulfame potassium, joins the existing sweetener aspartame.
