Aniston, 45, and Pitt, 50, ended their five-year-old marriage a decade back.
Pitt wed Jolie, 39, last year, while Aniston has been engaged to actor Justin Theroux since 2012, reported Us magazine.
Commeding Jolie's work on the World War II drama, which like Aniston herself, was snubbed by the Oscars this year, she said, "I mean, that movie is so beautiful and wonderful, and she did such a gorgeous job.
"I think it's time people stop with that petty thing and just start celebrating great work and stop with the petty kind of silliness," she said.
