Kardashian and partner Scott Disick are expecting a younger brother or sister for their son Mason Disick, who is nearly two.

The eldest Kardashian sister said: “Scott and I are so excited to announce that we are expecting our second child and are thrilled to be expanding the love in our family.”

The reality star, 32, has revealed that she is just nine weeks into the pregnancy.

She said: “Now I’m nine weeks along,’ Kardashian tells the magazine. ‘You’re supposed to wait 12 weeks to tell people, but I feel confident.”

Disick, 28, said: “It wasn’t like we weren’t trying. We kind of just said, “If it’s meant to be, it’ll be.’”

It is rumoured that Disick is planning to propose to Kardashian.

A source said: “He chose a 1.5-carat princess-cut diamond ring.”

Kardashian has just started a web series called Kourney’s Mommy Blog, spilling the beans on what she’s learned while raising Mason.
