Victoria's Secret Angel Alessandra Ambrosio Heats Up Sin City in Cut-Out Gown

Where does a Victoria’s Secret Angel go for some rest and relaxation? Sin City, of course. READ: Alessandra Ambrosio Reveals Her Favorite Workouts This past weekend, Brazilian bombshell Alessandra Ambrosio was spotted showing off her runway-ready assets in a gown that perfectly fit the theme of flashy Intrigue Nightclub in Las Vegas. A source for the venue reveals that the 35-year-old model rocked a revealing asymmetrical Versus Versace cutout gown — which gave a whole new meaning to the term little black dress. Ambrosio finished her look with Giuseppe Zanotti stilettos at the end of her long, lean legs, as well as a braided up-do to help her stay cool in the Vegas heat. The source added that Ambrosio and her friends, including fellow Brazilian model Fernanda Motto, were "surprised with a fanfare-filled champagne presentation." In addition, "the group then sipped on bubbly and boogied to the beat, enjoying a clear view of the club’s stylish interior and outside area featuring the iconic 90-foot waterfall and pyro show behind the DJ stage."
