Jennifer Aniston, Brad Pitt, and Angelina Jolie are among the A-list hosts of this year's Night Before pre-Oscar bash, Us Weekly reports in its latest issue, on newsstands now. The press-free charity event promises to be the first time Aniston and Jolie have met since Pitt left Aniston in 2005 and started a family with Jolie a short time later. "Jen wants to go but knows it would be a disaster waiting to happen," an Aniston insider tells Us. A source tells Us that Aniston will be at the event as long as her filming schedule allows. The minimum entrance fee is $25,000 for four tickets, with proceeds benefiting the Motion Picture and Television Fund. Just three years ago, the same party served as a backdrop for Aniston and Pitt's last public appearance together. Fresh off the announcement of their split, the duo worked the crowd side by side all night. Adding to the pressure: Jolie, who has said in the past she'd "welcome" a meeting with Aniston, will be receiving congratulations for her pregnancy. But Aniston seems ready. "She told me avoiding Brad and Angelina is more painful than seeing them," a pal told Us. A Pitt source tells Us that his attendance will be decided at the last minute, but it is traditional for all hosts of the party to attend.
