It's been nearly four years since Jennifer Aniston and Brad Pitt announced their split -- and Brad began his new life with Angelina Jolie. By all appearances, Jen has moved on.

But it turns out Jen is thinking about Angelina -- and hasn't forgiven the fellow actress for coming between her and Brad. Life & Style has learned exclusively that Jen discusses Angelina by name for the first time in an interview in the December issue of Vogue. "What Angelina did," Jen says, "was very uncool."

Her comment about Angelina, 33, is a huge surprise -- especially because Jen has carefully cultivated an image as a confident, sexy woman who doesn't dwell on the past.
