Justin Bieber & Kourtney Kardashian Heat Up Amid Baby Rumor: She & Kylie Jenner Compete For Sexy Pics [Photos]

Has Kourtney Kardashian become a rebel, flaunting her nearly nude body and dating Justin Bieber? Viewers of Keeping Up with the Kardashians know Kourtney as the oldest, soft-spoken sister. But since splitting from baby daddy Scott Disick last summer when he was caught cheating and drinking again, Kourtney has been turning heads by flaunting her revenge body and dating Justin.

Now the hot reality TV star is proudly puffing on a cigar and flaunting her fab abs and whittled waistlines amid rumors that she’s pregnant with Bieber’s baby. Kourtney increasingly has been showing her rebellious attitude to fans, even posting a photo showing her with that cigar, pointed out the Mirror.

Kardashian, who has three little children, made her defiant side clear in the caption to her photo as well.

“Who the F**K do you think I is?” demanded the 37-year-old.

But while Kourtney is having fun, she’s still paying attention to what the father of her children is doing.

Aware that Scott continues to party, Kourtney told her little sister Kylie Jenner that she blames Tyga, who is Kylie’s boyfriend, for encouraging Disick to party.

“It p**ses me off that people like Tyga, that should know better, that are close to our family, that don’t just find some other friends,” she said angrily.

And Kardashian made it clear to Kylie that she blames her boyfriend.

“It’s not like Kanye is calling him like, ‘Come to the studio,’ every night. ‘Come to my show!’. It’s Tyga calling him to hang out and go to parties. It still bothers me,” declared Kourtney.

However, Kardashian and Kylie do agree on one part of the responsibilities of a Keeping Up with the Kardashians clan member, and that’s showing off their bodies on social media.

Kourtney teased fans with her nude bodysuit’s caption.

“IN THE NUDE. On my app. #LinkInBio,” tempted Kardashian to get fans to her app.

But little sister Kylie wasn’t far behind when it comes to displaying her body. Jenner flaunted her own fab abs by showing a behind-the-scenes photo shoot for Glamour, noted the Daily Mail.

Kylie also proclaimed herself a feminist role model.

“I do consider myself a feminist,” declared Jenner. “I don’t depend on a man or anybody else. I feel like I’m an inspiration for a lot of young girls who want to stand on their own.”

And for those girls, Kylie also showed that they can compete with older sisters like Kourtney by posting her own barely-there-material photo.

While Jenner and Kardashian compete for sexiest photo, it’s Kourtney who is currently coping with baby rumors again. Friends of Kardashian’s have claimed that Kourtney is blossoming with a baby bump and that Bieber is the daddy, according to Hollywood Life.

“Kourtney’s already admitted to friends that she and Justin have been intimate, and she hasn’t been with Scott in a longtime, so the math is pretty clear. It would have to be a Bieber baby.”

As for the details of Kardashian’s romance with Bieber, People cites several insiders confirming that Kourtney and Justin are once again heating up their hookup.

Kardashian and Bieber have hooked up “on and off for a few months now,” said one of the sources. “Justin thinks it’s cool that she is older and hot. She isn’t clingy and has her own life.”

The two have repeatedly met up in Los Angeles, and although the pop star has met Kourtney’s children, they don’t hook up around her two sons (Mason, 6, and Reign, 1) or daughter (Penelope, 3), according to that source. Instead, they go out on the town when she has some help at home to care for the kids. And that hookup shows no sign of stopping, with both reportedly enjoying their friends-with-benefits arrangement.

But as for those Bieber baby rumors? Gossip Cop cited a source close to Kardashian who revealed that it is “not true” Kourtney is pregnant with either Disick’s or Justin’s baby.
