Kourtney Kardashian Pregnant With Baby Number Three?

The reality star reportedly expecting her third child with longtime boyfriend Scott Disick.

They say three's a charm. Kourtney Kardashian is reportedly expecting baby number three with longtime boyfriend Scott Disick. According to US Weekly the oldest Kardashian sister is only a few months along and the couple will welcome their new bundle of joy in December.

The pregnancy comes a little less than two years after the couple welcomed their daughter Penelope, who turns 2 next month. They also have a son, Mason, who is 4.

"It was planned," a source told US. "[Kourtney] wants to have a handful of kids."

The Kardashians have yet to comment on the pregnancy news, but Kourtney may have a hard time hiding her baby bump as she beats the summer heat in the Hamptons. Kourtney and Khloe are currently filming their new E! show "Kourtney & Khloe Take the Hamptons" in the upscale New York neighborhood. The sisters were spotted out together on Tuesday grabbing lunch at Zach Erdem's 75 Main.

The E! spin-off will follow the reality star sisters as they open their DASH boutique’s first pop-up shop in the coastal community and relocate DASH’s SoHo store in New York City.
