Sienna Miller hit the red carpet for her fiancé, Tom Sturridge, when she attended the Broadway premiere of his new play, Orphans, in NYC last night. She wasn't the only star who turned out to support the all-star cast, which includes Alec Baldwin and Ben Foster. Other celebrity attendees included Dakota Fanning, Winona Ryder, and Alec's 30 Rock costars Tina Fey and Jane Krakowski, who shared a hug at the afterparty.
Sienna has been spending her time with family in NYC while Tom geared up for his big premiere. Earlier this week, she attended the annual Tribeca Film Festival kickoff party with Tom's sister, Matilda Sturridge, and she also squeezed in a lunch date with her dad and stepmom on Wednesday. Sienna and Tom will spend the next four months in the Big Apple until the play ends in July.
