One of Hollywood’s newest romances may be over. Kourtney Kardashian and Justin Bieber have been rumored to be having a fling for several weeks, but it doesn’t appear the speculated couple rang in New Year’s weekend together.

After spending months claiming their relationship is platonic, Bieber, 21, shared a photo of himself kissing Hailey Baldwin on Instagram Sunday night. The captionless photo shows the "Baby" singer locking lips with the 19-year-old model while wrapping his arm around her. Bieber followed up the passionate shot with an image of him and Hailey dressed up and sitting side-by-side inside a lounge. 

While Bieber was busy locking lips with another lady, Kardashian found someone else to smooch. The 36-year-old mother of three and star of E!’s “Keeping Up With the Kardashians” revealed on social media Jan. 1 that her New Year’s kiss was with her youngest son, Reign. Kardashian welcomed Reign with on-again, off-again boyfriend Scott Disick in December 2014. 

Rumors about a potential romance between Kardashian and Bieber started in Dec. 11, 2015 when the pair were seen partying together at The Nice Guy in West Hollywood, California. “He and Kourtney were nearly inseperable,” a source told People magazine. According to the insider, they were seen smoking together and being “super touchy feeling.” Bieber fueled the rumors when days later he posted an Instagram shot, which many believed to be a dig at Disick, 32, who goes by the nickname The Lord. The photo in question showed Bieber straddling a female on the hood of a car with the caption “Lord Knows.” The woman in the photo was later confirmed not to be Kardashian.

If Bieber and Kardashian did go their separate ways, it doesn’t appear the singer will be heartbroken over their split. A source told People last month that Bieber isn’t taking their romance seriously. “He brags about how hot she is. He is happy while it lasts,” said an insider. “Even if she is using him to get at Scott, he couldn’t care less.”
