Yowza!

On Sunday night Kim Kardashian attended the Elton John Aids Foundation Oscar viewing party in West Hollywood, and the reality starlet showed off her curves in a very revealing red Celia Kritharioti gown. In fact, it might have been too revealing -- as far as we're concerned, only Kanye and Nori should be seeing that much of Kim's breasts!

Kim was joined by her sisters Kourtney and Khloe and their mom Kris, and the rest of the ladies went the more demure route with their fashion. Khloe wowed in a burgundy velvet gown, and she wrote on Instagram, "I'm in love with my @marcbouwer dress!!!! Thank you @robzangardi and @marielwashere for making me feel like Jessica Rabbit tonight."
