Dianna Agron led a pack of ready-for-Summer stars who attended Coach's Summer Party on the High Line in NYC yesterday. The public park was closed off for the event and filled with carnival games, like a dunk tank and fortune teller's booth. Penn Badgley attended without girlfriend Zoe Kravitz, and showed off a seriously bushy beard. Maggie Gyllenhaal also stepped out to check out the scene, as did Anna Kendrick, Kate Mara, Jessica Stam, Benjamin Walker, and more. Many of the ladies made the rounds carrying pieces from Coach's new Legacy Collection. Anna is hanging out in NYC after a clip from her new movie dropped this week. The Pitch Perfect trailer came out Friday, showing Anna taking a page from Dianna's series Glee and joining an all-girls music group.
