Kelly, Kourtney, Kim and Katy party with Elton John at the Oscars 2012

The Vanity Fair party wasn't the only celebrity hotspot post-Academy Awards last night. Elton John threw his annual Aids Foundation Oscars viewing bash at West Hollywood Park, which is basically where the A-list who aren't invited to the actual event hangout and watch the show.

One thing's for sure: Elton knows how to draw a crowd in. All the K's were there - Kelly Osbourne, Kourtney and Kim Kardashian and Katy Perry - along with Heidi Klum, Anna Paquin, Dita Von Teese and Gwen Stefani.
