Naturally, we suspect the doll belongs to Kourt's daughter Penelope, but the 37-year-old may be preparing for her own new addition in the near future. In Touch recently revealed the oldest Kardashian kid may be pregnant — only this time she doesn't know if longtime love Scott Disick is the father.

Unfortunately for Kourtney, the reality star was hooking up with boxer-turned-model Younes Bendijma during her reconciliation with Scott. "When she told pals a few weeks ago that she missed her period and fears she’s pregnant — she also said she didn’t know who the father is," a source revealed.

"Scott thought a reconciliation was in the cards for them, they had discussed having another baby," the source said of Kourtney and Scott, adding that during their Mexico vacation they failed to use birth control. "Kourtney is very fertile. She has a big problem."

The 33-year-old businessman "hit the roof" when he found out about Kourt's rendezvous with the 23-year-old model. "Kourtney has a thing for boy toys, and Younes is just her type,” the source continued. "She’s been boasting to pals about his amazing six-pack, telling them she can’t keep her hands off his sexy body."

This wouldn't be the first time Kourtney found herself in the midst of a paternity scandal. Following the birth of son Mason, model Michael Girgenti demanded a DNA test from the brunette beauty after he claimed they hooked up in 2009 during her break with Scott, nine months before little Mase was born. She agreed to the test, which ultimately proved Scott was the father.
