She’s tutu cute! Pregnant singer Beyoncé steps out in a fashion-foward first — a fitted jacket, flouncy, frilly tutu and chunky sandals — while sporting her new baby bump at Mercedes-Benz Fashion Week in Manhattan yesterday. The sexy singer, who’s married to rapper Jay-Z, hit some of the designer shows with sister Solange, even changing outfits along the way to show off her sassy style.
