Last November, Aniston joked to Ellen DeGeneres that her guests always assume that her parties will turn out to be her long-awaited wedding. Example: Sacha Baron Cohen and Isla Fisher. "They would show up in beautiful wedding wear," Aniston explained. "Even the 4th of July last year, they showed up, and Sacha was in a powder blue suit, and Isla was in a little cute dress. And we were like, 'Guys, it's the 4th of July. We're in cutoffs and eating hot dogs. We will actually let you know!' "
