Khloe Hosts Kim's Last-Minute Engagement Party

Khloe Kardashian, 26, helped organize a last-minute engagement party for Kim Kardashian, 30, and Kris Humphries, 26, this past Thursday. "We obviously move really fast in my family," Khloe told Us Weekly during the NIVEA Challenge in Bel Air, Calif. Sunday. To help organize the get-together, Khloe called upon party planner Sharon Sachs, who oversaw the E! star's wedding to Lamar Odom in 2009. Nearly 50 close friends and family members attended the celebration, including several friends who hadn't yet met Kris.
