Ashley Greene finished up a sweaty workout at the Tracy Anderson Method studio in LA yesterday. She's among the many stars getting in on the fitness craze, which also counts Nicole Richie and Gwyneth Paltrow as fans. Ashley was dressed down for the gym trip after getting glamorous at the CFDA Fashion Awards in NYC earlier this week. She attended alongside designer Michael Kors and posed with model Miranda Kerr on her way into the event. Ashley fit right in on the fashionable night, but she missed out on another fun evening at Sunday's MTV Movie Awards. Her Breaking Dawn costars were there to represent for the franchise and also debut a brand-new clip of the upcoming movie. Ashley hadn't even seen the trailer herself, since she was busy at a friend's wedding over the weekend, but she twittered her support for the rest of the cast.
