Sienna Miller to Make Broadway Debut

Is it just us or is Broadway rapidly replacing getting pregnant as Hollywood's latest career move?

Following on the heels of another celeb, a.k.a.-- Ms. Katie Holmes, Sienna Miller   plans to make her Broadway debut this fall in the Roundabout Theater Company's production of After Miss Julie.

Based on playwright Patrick Marber's 19th century Stringberg classic, the story focuses on sex, class and power. Miller, 27, will play the title character, Julie, a wealthy young woman involved with a family manservant.

No word on whether the actress's boyfriend, Balthezar Getty, will join her in NYC for the length of the show.
