Sienna Has Plenty of Company After the Show and Miss Julie

Sienna Miller joined her After Miss Julie costars Jonny Lee Miller and Marin Ireland onstage in NYC last night as they officially opened their Broadway show. The trio had a great deal of support for their big evening, with Anna Wintour, Rachel McAdams, Claire Danes and her new husband Hugh Dancy turning out to attend both the premiere and afterparty. True Blood's Alexander Skarsgard also made an appearance, though his rumored lady friend Kate Bosworth wasn't by his side. Sienna beamed in her shimmery short dress at the bash, but she might not be so smiley if she braves reading her reviews.
