After four years of near misses, Jennifer Aniston will finally come face to face with the woman who stole her man.

This Sunday Aniston, Angelina Jolie and Brad Pitt will all be in the same room together for the 81st Annual Academy Awards.

"She has always known that this moment would happen and she's never been more ready to see her nemesis, Angie, in the flesh," a source tells OK! of Aniston.

"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."

This should be juicy! Mayer recently told reporters that he'll be attending the Oscars "as a boyfriend" this year, so we already know Jenn won't show up without a date.

Knowing Jenn, she'll probably have her people make sure her and Angie are never within 25 feet of each other. Which couple are you most excited to see on the red carpet this weekend?
