OK! Exclusive: Kourtney Kardashian Slams Kim—Find Out How She's Taking Over The Family!

Kim Kardashian may have helped propel the family into superstardom, but Kourtney wants her to know she’s the head of the family now!

But Kim, 35, still thinks she’s the “puppet master” when it comes to her sisters. Little does she know that Kourt is over her antics. “She has every intention of putting her spoiled brat sister in her place.”

And she better move quickly! Kim is starting to take major jabs at her older sibling, and even her kids, as seen on a recent episode of their reality show.

Kim told Kourt about how she and North were looking at the stars and the moon when she pointed out the North star. And North said to her, “And a ‘P’ star, ‘Mason’ star,” but Kim replied back, “I said, ‘no there’s only a North star. P doesn’t have a star.” Ouch?!

And then Kim slammed Kourt again during a dinner earlier this year, telling her “you’re not special.”

Kourtney is taking back control slowly but surely, however. Added the insider, “She’s taking command and, let’s face it, of all the sisters she’s the only one with real brains and should never be underestimated.”
