Joshua Jackson was just one of the stars that participated in the 24 Hour Plays benefit in Santa Monica, CA, yesterday. The production raised funds for Urban Arts Partnership and also brought out Ashley Greene, Jason Ritter, Jessica Szohr, and Brooklyn Decker. Brooklyn shared a peek at her character, which happened to be a man, on Twitter, while Ashley wrote, "I feel like I was just at adult summer camp with the most incredible and talented people." Brooklyn will soon return to the UK, where she traveled from to make the fund-raiser. Joshua, meanwhile, has been hanging in LA with girlfriend Diane Kruger, and the duo have shared multiple date nights during their time on the West Coast.
