Sienna Miller will make her Broadway debut with the British adaption of a famous play by Swedish author August Strindberg called "Miss Julie".

Sienna has played this role before in London, but she says she is very anxious about performing in New York, she knows this could make or break her career!

Her friend actor Peter Sarsgaard has some good advice: "hire a masseuse".

 Sienna will need one if she is going to be performing 8 times a week!

She's looking dazzling in this Lady Gaga-esque dress here!
