says Angelina Jolie
has a lot to learn about being discreet.
In an interview in the December issue of Vogue
, out Nov. 19, 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 circumspect 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, 39, 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."
Aniston also opens about her own romantic life, post-Pitt, including a much-discussed on-again, off-again relationship
with 31-year-old musician John Mayer
, who she says has matured
since they've been together.
Rumors that she is "clingy" or "needy" in love are off-base, she says.
"This whole 'Poor lonely Jen' thing, this idea that I'm so unlucky in love? I actually feel I've been unbelievably lucky in love," she says.
