Four years have passed since the world buzzed about the Jen-Brad-Angie love triangle. Angelina Jolie and Brad Pitt now has three kids of their own. Jennifer Aniston has dated Vince Vaughn and has an on-again-off-again relationship with John Mayer.

Ever since Brad split from Jennifer in January 2005 and made babies with Angelina, everyone has been waiting for this showdown. For the first time, Angelina and Jennifer will finally see each other at the Feb. 21 ‘Night Before the Oscars’ party in Beverly Hills.

According to OK! mag, a friend close to Jennifer Aniston says, “She (Jennifer) has always known that this moment would happen and she’s never been more ready to see her nemesis, Angie, in the flesh. She’s no longer alone — she has a hot man in her life — John Mayer — and she plans to bring him as her date to the party. It’s taken time, but she’s getting past her insecurities about Brad and Angie and their huge happy family. Though the meeting is sure to be difficult, Jen knows it has to happen and now couldn’t be better timing.”

What does Angelina Jolie think about the event?

Aside from her man Brad Pitt being nominated for his “Curious Case of Benjamin Button” film, Angelina also has a nomination for her work on “Changeling.” According to OK!’s insider, “They’ve shown up for every major awards show and have every intention of enjoying themselves at the party. They don’t consider it Jen’s turf.”

Jolie may seem confident, but the Changeling star is reportedly looking for a $20-million necklace while in New York to show off at the Oscars. Can this be related to Jennifer Aniston being a presenter at the awards show? Are we smelling a bit of insecurity here? Can’t wait to watch the Academy Awards and capture the reactions of these celebs!
