Oscar-winning actress Rachel Weisz is celebrating after giving birth to her first child on Wednesday (31MAY06). The English movie beauty, 35, and her American director fiance Darren Aronofsky welcomed a baby boy in a New York City hospital, near the couple's Manhattan home. THE CONSTANT GARDENER star's spokeswoman KELLY BUSH declined to give the baby's name or weight, but declared mother and baby were "happy, healthy, wonderful". Weisz started dating 37-year-old Aronofsky in 2001 and moved from her native London to live with him in New York. They announced their engagement last year (05). Weisz, who won an Academy Award in March (06) for her performance in The Constant Gardener, stars in Aronofsky's forthcoming sci-fi drama THE FOUNTAIN.
