Lovebirds Renee Zellweger and Bradley Cooper shared the big screen in the movie which is said to have sparked their romance. The couple, who have been dating for 12 months, enjoyed a tender embrace in horror film Case 39. While Zellweger, 41, plays social worker Emily Jenkins, who is assigned to investigate the family of a 10-year-old girl, 35-year-old Cooper plays her psychiatric best friend Douglas Ames. But unlike real life, things do not run smoothly for their respective characters. After Emily gains custody of 10-year-old Lillith Sullivan, strange things begin to happen around her and her work. While Case 39 was filmed at the end of 2006, Cooper and Zellweger did not begin dating until August last year. They have since met each other's parents and enjoyed holidays in Vancouver, Canada, and Barcelona, Spain. The couple are notoriously private about their romance and often go to great lengths to avoid being photographed together.
