Justin Bieber, Hailey Baldwin Romance: 'Sorry' Singer Spotted Getting Cozy With The Model; Kourtney Kardashian Got Pissed With The Two?

Days after the announced fling with Kourtney Kardashian, 21-year-old singer Justin Bieber showed a lot of PDA with his long-time friend Hailey Baldwin throughout the week up to New Year's Eve at Richie Akiva's party on St. Barts in welcoming 2016.

According to E! News, the couple doesn't have a label and isn't official yet. "Hailey and Justin have a very tight relationship. They both are very close with each other's families and care very deeply about each other. Hailey's family has been there and supported Justin through his transition so Justin has a strong respect for them," a source from E! News said.

In addition, a source from Realty Today reported that the 19-year-old model seemed serious with her relationship with Bieber and will do everything for it to be really official.

"She is ready to give him everything, it's now his move! Hailey really likes Justin a lot, and he takes it much more leniently," a source said. "She stays around because she hopes that she will convince him into a relationship and he is more about the friends with benefits. She is going to stick around until she changes his mind."

The duo has been posting a lot of their photos together on social media, making the fans go crazy. Baldwin even posted a photo of her on Instagram with the "Sorry" singer wearing a short cutout cocktail dress while wrapping her arms around Bieber from behind.

Meanwhile, a source from TheHollywoodLife.com reported that Kourtney Kardashian might be a little jealous and upset with the new flame but for her it isnt a big deal after all. "She thought it wouldn't bother her, but deep down it does. It's just a wake-up call that her romance with Justin would never evolve into anything serious," the insider claimed. "Once again, she's putting on a happy front for the kids and acting like it's no big deal."
