Khloé Kardashian's Reaction to Kim's Second Pregnancy Is Pure Gold

Khloé Kardashian was one of the first people to know about her sister Kim Kardashian's second pregnancy, and in a new sneak peek from the upcoming season of Keeping Up With the Kardashians, you get to see just how she reacted. Kim, who announced in June that she's expecting a baby boy with her husband, Kanye West, told Khloé the exciting news behind closed doors. "I haven't told anyone," Kim said. "I told North last night, but I don't think she understands." After Khloé screams in excitement, she tells the camera, "I'm just happy that my sister's pregnant. I'm excited. I want there to be more kids." Things then take a hilarious turn when Khloé gets brutally honest with Kim about what the pregnancy means for her. "I really thrived when you were fat and pregnant and they compared you to a whale," she told her sister. "That was the first time I was ever the thin one."
