The Kardashian Sisters: The Baby Rush Is On!

By this time next year, there could be as many as three new babies in the Kardashian family! This week's issue of OK! has all the details on Kim, Kourtney and Khloe's plans to expand their families.

Though she and NBA star Kris Humphries were just married last month, Kim, 30, has wanted to become a mom for a long time.

In fact, she may already be pregnant, as she recently Tweeted about her "cravings." A pregnancy for Kim would also delight her mom, Kris Jenner. "Kim will be the perfect mom," Kris tells OK! exclusively. "She is just someone who is so filled with love."

Don't be surprised if the next 12 months bring a new baby and wedding bells into the lives of Kourtney and Scott Disick (the father of Mason, Kourtney's 21-month-old son). A sibling for their son will probably come before the wedding though.

"We're in no rush" to be married, Scott tells OK!, though he admits that a wedding will "absolutely" happen.
