Kourtney Kardashian is upset over Justin Bieber's comments in radio interview and wants an apology.

Kourtney Kardashian Speaks Out After Justin Bieber Claimed That He Was ‘Used’ By Her In Their Short-Lived Romance

Kourtney Kardashian feels betrayed over the comments Justin Bieber recently made about their romance during his radio interview with The Bert Show on Monday. When asked about Kourtney, Bieber said he was “used,” supposedly so that she can get back at her ex, Scott Disick. The comment sounded like it was made in jest, but the 36-year-old mother-of-three wasn’t laughing and went so far as to demand an apology and an explanation from Bieber.

Kourtney is both shocked and hurt with what Justin had to say. She has been nothing but respectful towards him and their relationship. She has been so protective of him and now she feels completely stabbed in the back,” a source told HollywoodLife.

During the interview, Justin spoke up about his much-talked about romance with Kourtney, confirming the hookup rumors that circulated across media channels over the last three weeks.

“I’m being used, man. What can I say?!”

Lord knows

Going by the interview, Justin’s words have to be taken with a grain of salt. Radio host Bert Weiss should know, as he was the one who saw Bieber’s body language during the interview.

“But, honestly, I’m not sure he was 100% with us on this one. Body language and words didn’t match,” Bert said when he responded to a fan.

Admittedly, whether Justin was joking or not, those words sounded a bit too harsh, especially on account of what Kourtney has been through — and is still going through — lately. In last Sunday’s episode of Keeping Up With The Kardashians, Scott Disick appeared repentant when he broke down in tears in front of Kourtney and her family. Just when fans thought the former lovers are getting back together, news broke revealing that Scott Disick has recently hooked up with a Swedish model, as reported in the Inquisitr.

Also, Kourtney’s partying has recently gotten out of control, according to another report by the Inquisitr. Is it a coping mechanism on her part? It’s easy to assume so. If we look at it from that context, Justin’s humorous jab at their romantic tryst sounds too close to home. But then again, the part that pissed off Kourtney was that Bieber had to say it in public, especially considering the fact that they both agreed to keep their mouths shut about what went on between them.

“She thought they were friends and Justin has not been acting like a friend at all. They both promised each other that they would not discuss their relationship with anyone, and then he goes and disses her in public.

“Kourtney wants a major explanation and apology. She’s not the one who leaked their romance to the public. She feels like she’s being punished and it just goes to prove her initial instinct — that Justin is too young and too immature for her. She’s kind of beating herself up for ever getting involved with him in the first place, and not listening to her gut. She really regrets the whole thing.”

After all is said and done, it’s clear that the short-lived romance between Bieber and Kardashian was nothing too serious. In fact, Justin’s been getting cozy with another woman lately. The “Sorry” singer has been reportedly dating Hailey Baldwin, 19, since Christmas. They’re not shy about piling on the PDA too, as the Instagram photos posted below can attest.

“Justin has been friends with Hailey for a long time and he can trust her,” an insider told HollywoodLife. “These other girls are nothing more than a good time — that includes Kourtney. He was never going to settle with Kourtney or these other girls because they have baggage.”

Well, it’s clear that the past few months have been an emotional roller coaster for Kourtney and fans can only hope that she can finally catch a break. On the positive side, there’s one thing that she’s always got going for her: the constant love and support of her Kardashian sisters.
