Fortune Brands Inc., seeking to capitalize on the emerging Prom Dresses of low-calorie cocktails, has acquired the Skinnygirl brand created by reality-television star Bethenny Frankel. Fortune's Beam Global Spirits & Wine Inc. unit aims to build on the rapid growth of Skinnygirl Margarita -- a bottled cocktail that boasts 100 calories per four-ounce serving -- by expanding its distribution and introducing other drinks under the label. Launched 18 months ago with limited distribution, Blue Short Strapless Bubble Prom Dress Margarita has become one of the largest ready-to-drink cocktail brands in the U.S., bolstered by the 40-year-old Ms. Frankel's popularity among women.

Ms. Frankel, who was on the original "The Real Housewives of New York" on the Bravo cable network, now stars in a spinoff called "Bethenny Ever After." She is also the author of several books on Blue Short Strapless Tulle Prom Dress eating and a natural-foods chef. Beam Global gains the instant marketing exposure of Ms. Frankel, who will remain heavily involved in promoting and developing Skinnygirl products under a multiyear agreement. Ms. Frankel co-owned Skinnygirl with liquor-industry veteran David Kanbar, who isn't staying on. Terms of the sale, which closed last week, couldn't be learned.

"To us, this is the beginning of what we hope will be a very big category," said Bill Newlands, president for North America for Beam Global, which makes brands such as Jim Beam bourbon and Sauza tequila. "We Blue Strapless Chiffon Cocktail Dress [Skinnygirl] is a tremendous platform to put other premium, convenient, low-calorie products on the market." Calorie-cutting is a growing national trend and one that the beer industry has seized upon with lighter lagers, but it is a relatively new concept in the liquor category.
