Katie Holmes Hits Up "August: Osage County"

Katie Holmes stops in to see a performance of August: Osage County, the Broadway transfer of the hit play by Tracy Letts from Steppenwolf Theatre in New York City on Tuesday night.

The 29-year-old actress rocked out a pair of brown five-strap shoes but strangely enough had bruises all over her knees.

August: Osage County is about a vanished father, a pill-popping mother and three sisters harboring shady little secrets. For more info, visit AugustOnBroadway.com.
