Jennifer Aniston turned up the heat in Canada as he showed off her stunning figure in a revealing black dress.

The 39-year-old, who is appearing at the Toronto Film Festival to promote her latest movie Management, has been looking better than ever since her split from singer John Mayer last month.

Rumours are circulating today that the former Friends star had a business dinner with her ex-husband, Brad Pitt, last night at the festival.

If true, it would be the pair's first known meeting since their bitter divorce in 2005.

Prior to the festival, the actress was said to have been terrified of accidently bumping into the 44-year-old and her team was reportedly working hard to ensure the two do not cross paths.

'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,' a friend is quoted as saying by Now magazine.

'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.’

Pitt will debut his Coen Brothers movie Burn After Reading at the festival on Wednesday.

His partner Angelina Jolie will not be attending and is expected to remain in France with newborn twins Vivienne and Knox.
