Kelly’s water weight.

Ever wonder what Kelly Clarkson and 50 Cent could possibly have in common? No, it’s not a love of ProActiv Solutions (that would be Kelly and P. Diddy), but an affinity for Vitamin Water. Last year, the rapper endorsed an exclusive Vitamin Water flavor of his own and this year, Page Six of the New York Post reports that Kelly’s slated to do the same. But before audiences can get a taste Kelly’s flavor, she’s been put on a diet by Vitamin Water manufacturers. The company, whose product claims to have 50 percent of the daily vitamin requirements a person needs, wants to ensure that Kelly’s image is in line with their product’s promise to promote a fit and healthy lifestyle. So, 50, lay off on the offers to take Kelly to the Candy Shop.
