The Kardashian clan is known for doing everything as a family. So when the oldest Kardashian girl, Kourtney, 30, happily announced on Aug. 12 that she was around five months pregnant, her sisters were by her side to show their support. "I'm very excited to be an auntie," Kim, 28, tells Life & Style. "It's a very exciting time in all our lives."

And 25-year-old Khloé, who's been on a whirlwind tour with Kourtney to promote their new E! reality show, Kourtney & Khloé Take Miami, has taken on the role of on-the-road mom. "I feel like I have to take care of her more," Khloé told Life & Style at the sisters' Aug. 16 party to celebrate the show at Wet Republic in Las Vegas. "She says, 'I'll just have a banana for breakfast,' and I'm like, 'No, no, no, I have to make you pancakes with bananas.' I'm a little crazy."
