Diet Pepsi is rolling out limited-edition 7.5-ounce cans featuring a design by HGTV star Vern Yip. The blue-and-gray printed can features a peacock, and is part of the brand's "Love Every Sip" 2013 campaign targeting women. Why a peacock? "It does a great job of representing confidence, vibrancy, positivity, energy and strength, which are all attributes of our Diet Pepsi consumer. We think it really fits in well with her lifestyle," said Amy Spiridakis, director of marketing for Diet Pepsi.
