Nicole Richie oscars.jpg...at an Oscar afterpar-ty! We spotted Nicole Richie and Joel Madden all over each other outside Patrick Whitsell's post-Oscar shindig before leaving (with Mischa Barton), and according to our spy, they were just as affectionate inside the party! (Could this have something to do with Richie's new rock?) We also spotted Cameron Diaz (who our insider saw flirting up a storm with Djimon Honsou - you heard it here first!), Jessica Biel, Leelee Sobieski (who looked glorious in her gold dress), Joe Francis, and Martin Scorsese's #1 fan Courtney Love!

We've got plenty more to come from this bangin' party, so stay tuned to X17!
