Actress Rachel Weisz, who is seven months pregnant, strolled around SoHo yesterday afternoon with director boyfriend Darren Aronofsky, 37. Weisz, 35, is the new face of Burberry's ad campaign for the new fragrance London, which she shot last October with Ioan Gruffudd. "I'm British. I grew up with Burberry being the ultimate brand in chic, elegance and history. My granny, the chicest lady I ever knew, had a Burberry raincoat. Now it's a cool and edgy fashion house, too. I was thrilled to be asked (to model). There was no hesitation."
