According to the mag, a friend of the star revealed the engagement news. But Leelee herself showed off a rock on her ring finger at the LA premiere of her latest film, "Public Enemies," on June 23.
The actress, whose film credits include "The Glass House," "Never Been Kissed" and "Eyes Wide Shut," has served as a muse to her new fiance, modeling for his Fall/Winter 2009 Look Book. In one photo, the star dons a patriotic red, white and blue one-piece and a navy blazer.
