Jennifer Aniston saw ex-husband Brad Pitt with his new love Angelina Jolie for the first time yesterday (22.02.09).

Jennifer attended the Oscars with boyfriend John Mayer, and was sat around 12 seats away from Brad and Angelina.

The former 'Friends' actress presented the award for Best Animated Feature with Jack Black and as she made a joke about Jeffrey Katzenberg, the co-founder of animation company Dreamworks, Angelina laughed.

As Jennifer announced the nominees she moved to the centre of the stage - right in front of Brad and Angelina's table. When the lights went down, she smiled directly at Brad.

Jack Black said afterwards: "Jennifer did fine. She's a pro." Jennifer and John then clapped while Nicole Kidman introduced Angelina as a nominee for Best Actress, and while Brad, 45, was announced in the Best Actor category nominations.

The night before the Oscars, Jennifer held a pre-show party at her $15 million Beverley Hills estate. Around 100 guests attended, including actors Courteney Cox, David Arquette and Tobey Maguire.

Earlier in the evening, Jennifer briefly attended the Night Before charity event at the Beverley Hills hotel, but sources say she quickly left when she thought Angelina - who met Brad on the set of the film 'Mr. and Mrs. Smith' while he was still married to Jennifer - was also headed to the party.
