The Rocket Man sure knows how to throw a party!

Kim, Kourtney and Khloe Kardashian managed to break away from filming their reality show to attend Elton John's Oscar bash last night, and the sisters rubbed elbows with tons of their celeb friends, including Nicki Minaj! Other pals at the party included Miley Cyrus, Kelly Osbourne, Molly Sims, and Carmen Electra, among others.

Pregnant Kimmy K donned a white gown that showed off her growing baby bump, while Kourtney kept it conservative in a floor length red and black floral dress. Although they looked amazing, it's Khloe who we think hit it out of the park with her fashion choice! Clad in a neon one shoulder dress, Lamar Odom's wifey managed to steal the show from her famous siblings!

The spotlight will be back on Kim soon enough, though! Due in July, the brunette beauty is expecting a baby girl with Kanye West, according to reports.

We wonder if Miss Minaj and Khloe talked about American Idol vs. X-Factor?
