JENNIFER Aniston doesn't want to come face to face with ex-husband Brad Pitt in Canada next week. The pair is both due to attend the Toronto Film Festival to promote new films but Jen's team are working hard to ensure the two won't meet. 'Her people are checking and double checking her schedule to make sure she doesn't go within a mile of Brad, let alone bump into him,' says a pal. 'She's already concerned about her break-up with John Mayer overshadowing her movie, so the last thing she wants is another ex in the picture. It's inconvenient having to duck and dive but more than anything she finds it embarrassing." Jennifer, 39, is promoting Management, while Brad, 44, is publicising Burn After Reading. Angelina Jolie, 33, is expected to remain in France with new twins Vivienne and Knox. - NOW
