Kourtney Kardashian and Justin Bieber: Magazine claims reality star is pregnant

Kourtney Kardashian is pregnant with Justin Bieber's baby, Life & Style magazine has claimed. The two celebrities had briefly dated in December despite the 14-year age difference.

"Kourtney's already admitted to friends that she and Justin have been intimate, and she hasn't been with Scott [Disick] in a longtime, so the math is pretty clear. It would have to be a Bieber baby," a source reportedly told the magazine. The 22-year-old singer wants to be a father and he "is telling friends that the Kardashians are already like family", the source added.

The source apparently also said: "Kourtney has raved, 'The sex is really good and he makes me feel young again.' She is acting like a giggling schoolgirl in love." The two have also been reportedly going to church together.

"Kourtney is tired of being the boring, responsible Kardashian. Justin is helping her come out of her shell and that is why they are spending more time together," HollywoodLife had earlier reported citing a source. "She likes all the action around him. Kourtney wants to be young and free again like her much younger sisters and Justin does that for her," the source had said.

Meanwhile, Bieber's ex-flame Selena Gomez, 23, is apparently not happy with the pregnancy report regarding Kim Kardashian's sister, which she thinks is "stupid". "She doesn't think it's real but also doesn't want to think about it or talk about it. She is just mad that if she does an interview in the near future she will have to dodge the question," a source told HollywoodLife.

"She doesn't want to be put in that predicament. She hates having to deal with the eventual Justin related questions that she always gets, she wants to be asked and known for more than just him," the source said.

However, Gossip Cop reported that reality star's pregnancy report is "all lies". "We're exclusively told the star is absolutely NOT pregnant with Bieber's baby. A source close to Bieber also tells Gossip Cop exclusively that the allegation is 'B.S.'," it reported.
