Kim Kardashian on Preggers Kourtney: She's Huge!

Kim Kardashian is in awe of famous women who have bounced back from babies -- "Jennifer Lopez, Halle Berry and all the women who've had babies and still managed to look amazing" -- and now she just hopes her sister Kourtney will be one of them!

Kim's admiration for those women has grown as her sister's belly has expanded, telling OK! at an event for the Brent Shapiro Foundation for Drug and Alcohol Awareness she looks up to them "especially since my sister Kourtney is pregnant and I’ve seen how huge she’s gotten and I really hope she can go back and look amazing like she did before."

But?

"But I’m a little nervous for her," admits Kim, "because she's really big."

Ah, sisters!
