Katie Holmes, Naomi Watts, and Anna Kendrick teamed up at Coach's Summer Party on the High Line in NYC yesterday. The three women were joined by Nashville star Connie Britton, Revenge's Joshua Bowman, and model Chrissy Teigen as they mingled with New Yorkers at the park. Katie is currently filming her new project, Mania Days, in the city, and she caused quite a stir on set a few weeks ago when she was spotted filming love scenes with costar Luke Kirby out in public. Meanwhile, Naomi has been playing social butterfly in the Big Apple while her longtime love, Liev Schreiber, finishes up filming for his new project, Ray Donovan, in LA. Naomi hit up Stella McCartney's Resort 2014 presentation with friends Cameron Diaz and Kate Bosworth on Monday and joined forces with Sienna Miller at a charity event last week. She has big news to share today as the new trailer for Diana, her film about the life of Princess Diana, was released online.
