Beyonce Knowles is "Obsessed"

Hard at work at a Los Angeles studio, Beyonce Knowles was spotted filming a scene for her new movie "Obsessed" on Monday (June 23).

"Obsessed" tells the story of "a successful professional man with a beautiful wife who finds his idyllic life threatened by a temp in his office who reveals herself as a stalker."

Co-starring alongside the 26-year-old "Irreplaceable" singer are Stand By Me stud Jerry O'Connell and sexy Heroes actress Ali Larter, among others.

Still in the early stages, the Steve Shill directed thriller/drama doesn't find its way to theaters until its slated February 27, 2009 release date.
