Jennifer Aniston says Angelina Jolie has a lot to learn about being discreet.  In a magazine interview, Aniston says that, though there's no love lost between her and the woman who ended up with ex-husband Brad Pitt, Jolie should have been much more discrete about the romance, which blossomed while Pitt and Aniston were still married.  "There was stuff printed there that was definitely from a time when I was unaware that it was happening," Aniston says of comments Jolie had made to the same magazine a year earlier. "I felt those details were a little inappropriate to discuss. ... That stuff about how she couldn't wait to get to work every day? That was really uncool."
