Ashley Greene starts to pull out her ponytail as she watches day number twelve of the 2011 US Open held at the USTA Billie Jean King National Tennis Center on Friday afternoon (September 9) in Flushing, New York City.

The 24-year-old actress tweeted that she was headed to the event after shooting the new mark girl campaign. “At the @markgirl Spring 2012 photoshoot – loving the bright color trend!” she teased about the new look.

Ashley will be honored at the 2011 Toronto International Film Festival tomorrow afternoon with the Spotlight Initiative Award.

The Spotlight Initiative was created in 2008 to support independent films with messages that make a positive difference in the world and celebrate the art and craft of filmmaking for their social relevance.
