Well, we know Jennifer Aniston and Angelina Jolie have competed over magazine sales (not to mention the affections of Brad Pitt), but now are they competing over charitable contributions?

Earlier today it was reported that Brangelina had given away approximately $10 million dollars to various philanthropic organizations, and now Jennifer is set to announce "big news" on the season finale of Oprah's Big Give, according to Us!

No one's dishing on exactly what Jen will be doing on the show - but if she's gonna outshine her ex, it's gonna have to be major!
