OK! is reporting that Jen "She 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."
Apparently Jen has felt very confident ever since reuniting with John Mayer last year after their brief breakup. "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."
